I was spending a lot of time through this business model as well. I would go through the cold calling process which wasn't all that time consuming. But then I would create mock ups for all of my meetings and since I live in the city it was also not easy walking + train/bus all day long going to these meetings.
It was also discouraging that when I google mobile websites or some form of it, there are people basically giving away sites for pennies. Even on fiverr, there are an endless list of people willing to build sites for $5.
It's making me debate giving these websites away for free as long as they sign up with hostgator and I'd get as much as $125 referral fee from them ($125 if you sign up 21+ clients in a month).
Is anyone else using this business model? Would love to hear of people's experiences.
