In my opinion, it is going to be difficult to make money off of either. I don't see a lot of "mom and pop" businesses shelling out cash for customer service training. To me, customer service is something large corporations spend money on improving once they have finished with sales training.

The online idea - you are talking about competing with a place similar to this forum. Would you have posted this question on a site if you had to pay for the answer? I think the information is just too available, especially when you have to compete with Yahoo answers and Linked In. Have you ever been to Linked In's question section? They do for free what you would charge for, and you get to network there at the same time.

The best way I could think for you to make this a success would be to get subsidized by the state or Fed Govt. There are usually procurement dollars out there for teaching business owners how to do business with the federal govt...or some other new business skill. Kind of like subsidized SCORE counselors. There was a woman who did this in my area and was modestly successful.

I agree that there is a big lack of personal service in business these days. Good Luck.
