Is GF able to function similar to LendingTree.com's multi-step form?
Even if custom coding is involved, I am willing to pay to make this happen!
That is a very custom application. Gravity Forms can do things similar to that, but for a complete application like that, you would have to hire some help. Gravity Forms / Rocketgenius does not take on custom development like that. You can use our job board or any of the WordPress-related job sites out there. http://www.gravityhelp.com/forums/forum/job-board
