Question 2: Do you think there is big enough market for the service AND the market is easy to reach (without spending bootloads of money)?
Isn't figuring out how to convert your market into customers without going broke the definition of the startup process? I think the answer to this question must be "I don't know, working on it" or you're probably delusional.
My take on startups is little different. I like to believe that customers are already there, you just need to find them. Converting market into customers sounds like you need to "create" and "educate" a market which can be very hard.
