I would think that the two classic customer groups would be:
- Realestate Agents
I have just sold 2 panos to a town (both panos less then 140 kb)
I never experienced that any customer group is more likely to buy panos then the other. I have sold to movietheatres I thought they would never buy and have not sold to Ski-Resorts I was 100% sure they would by.
I allways depends on various factors like:
- do they have spare money
- is the responsable person fond panoramas
- do they have a own photographer
- the day mood of the person you talk to
I guess it's like any other work. You have to earn your money.
