It takes work to make the phone ring. It takes even more work to increase the sales ticket. Customers are looking for a contractor to do a little work. If you offer three options, do you find customers usually choose the middle option?
When trying someone new, they may go with a "Low Risk" by prepaying for services on a "Deal" on a contractor lead generation service. The deal allows them to set a "budget." It allows them to try you out before mentioning any additional details.

Not likely.
