I wonder if people here are making enough money to justify the time and money they invest in it?
How many customers do you guys have?

I don't think number of customers matter as much as profit. As you know, a lot of hosting companies are offering their services very cheap and do not calculate the cost of time they put in, or the cost of hiring new staff when needed, etc. This way, they can get a lot of customers with very little profit or no profit at all per customer. Most hosting companies that have made it and are most successfull would rather have 10 customers paying $20 each than 100 customers paying $2 each.

very good call mr amazon. the $20 a year hosts are gonna have to sell a whole truckload of accounts to be paying for their meals :)

but to answer your questions kickster...

a) not yet - just ask my bank manager...
b) not enough to justify the time and money i invest in it :D
