You're probably not in their target market anyways. The people who will willingly submit these forms are less technically inclined and have big headaches that they will spend money on to solve. I hate this approach as much as the next guy but I've come to respect that they still work very well. For products that don't work well as self-service (and there are many), you almost have to talk to a customer before you can close them.

These forms can actually help segment your customers and reduce sales cycle times when used appropriately.
