IT businesses here are already mature, from selling SOA to network and data center infrastructures. Most SME's use garbage for their intranet and few use centralized storage (with backups) - most won't/can't pay for it.
The KTVs are fantastic businesses as their intranet requirements are world-class - streaming interactive video, etc - but this is a closed market to newbies with crappy communications skills - and that one-year visa is a killer - makes EXPATS look unreliable as the buyer never knows when you'll decide to bolt.
I disagree with tigertiger on quality focused - Salvador's is an example of quality balanced with social responsibility while retaining cost competitiveness. I've said this many times and will repeat - Salvadors has the best service staff I've EVER seen in my limited time in Kunming. They're well trained, diligent - but perhaps more importantly - they seem genuinely happy. Even 5 star hotel restaurant staff appear like lazy imbecilic morons who'd rather be elsewhere (aside from the front desk staff, the concierges, and the porters).
For expats - expat services are a good way to get your feet wet - your entrance barrier is natural - the language impediment. The question for Kunming is - "can the expats afford the premium and will they pay it". Perhaps a good thermometer would be the organic grocery sales that occur. I'd definitely use the home delivery service for dry goods and heavy stuff (cooking oil, dishwashing detergent) - however to start such a business - you'll have to beat Metro prices and keep the delivery fees down.
My old buddy up in Beijing shuttered his home delivery services because he couldn't control the delivery costs - basically he was subsidizing his drivers. Even buying his own transportation couldn't solve his distribution fees (door to door service) - that and sourcing from Metro was just not as competitive as a trip to carrefour or metro.
Great concept - but he couldn't control the unskilled labor costs. If you want to know about that in person - go chat with the Lazy Bones owners.
For the high-end - example GNC - if GNC wants long-term penetration into this market - you'll have to provide a robust business plan with exceptional long-term revenue assurances - not to mention severely slamming the counterfeiters (long jail terms for endangering public safety - but we won't discuss the death penalty for that here).
Schools are a great concept - the schools here suck - 70 students per class? Half the class don't care about their grades - it's just free daycare for the kids. There are international schools which are allegedly pretty good - but how about foreign run schools for locals - stressing quality education and serious prep for the gaokao or foreign university admissions - this is where your english skills will shine.
Kunming's locals are getting wealther - so it you have the ability - overseas investment opportunities and portfolio management (as well as a way to move money offshore legally) is definitely in the cards - aka wealth management - offering residence, citizenship, etc - bearing in mind that if you guarantee residence or citizenship - you're a fraud (or a criminal).
One thing lacking from Chinese investments is clarity and disclosure - so being honest - allowing the investor to know all the known risks and how to mitigate them would be refreshing. This is something no local or even wealth management division of a bank can perform effectively.
Websites - low to no entrance barriers - especially in copycat land - although gokunming seems to have the corner on the kunming market for expat info.
Another service is after school tutoring. I have an after school tutor tutoring my kids (cuz my language sucks). My daughter's classmate's parents found out (not a secret) and now their daughter also comes over every evening (somewhat reluctantly I might add).
So comprehensive after school tutoring aka cram schools - they're all over Japan - so I'm wondering why the lack (or maybe I can't read the signs) of legitimate cram schools here.
As for hedgepig's comments - if you KNOW the market is protectionist/racist - you're one step up - it's the unknown things that you can't or don't plan for that are fatal. Keeping a low profile is mutually contradictory as business requires a high profile, heavy self promotion, and advertising (free if you know how to do it).
So if you want to start a biz - FIRST look for the natural or artificial entrance barriers and how long can they be effective to protect your monopoly while it incubates. Also - always have multiple exit strategies - ranging from business failure to M&A or if you're extremely talented and lucky - IPO. If you're new to entrepreneuring - look for opportunities that have rapid - preferably immediate - cash turnover potential with low or controllable risk. Ventures which require long lead times before generating revenue tend to fail and remember - in the USA 98-99% of all startups fail in the first year - so try to minimize the damage to your pocketbook - leverage whenever possible.
If you get knocked down - learn your lesson(s), get back up and go at it again - but remember to be realistic - don't fall in love with your dream to the point of self-delusion.
