I think the guys above offer good advice. From a commercial perspective let me give you another option.
DSLR's are selling at alarming rates these days.
The most popular buys are now under £500.
So your biggest potential market with cameras are those buying the entry models to DSLR. On this basis I'm going to make some big assumptions here ..... slam me down, anyone if you think I'm wrong .....but remember I'm trying to keep a commercial head on here & iidentify the biggest market.
- Majority of buyers are upgrading from point & shoot compact
- Most just want to get better pictures, expecting DSLR to offer that
- Most don't want to spend contless hours / days learning before getting good shots
- 10% of purchase price for training might be limit for buyer
On this basis I reckon if you could setup a hands on half day course for £50, that could have the photohgrapher leaving with basic understanding how to use the best Automode for their needs, taking a shot with reasonable composition, you could be on for a winner. If you could setup an environment where with their own camera they could capture a shot with short DOF for impact (say a lone flower) , a high & slow shutter speed example (say running water frozen & then blurred), plus then some basics exposure & composition, you could have people walking out after half a day shooting with much improved shots. Minimal overheads for you also.
I would say people on this forum are in the minority of DSLR owners, who are willing to spend time & effort to get where they want. We live in a society of "want it now", so commercially why not exploit it
Just another take & I'll let others get back to your initial thoughts
