Need help with search form plugin!!

Hi guys!
I am hoping someone can enlighten me with this problem. I cant seem to find a plugin that enables my website users to submit a multi step search form in order to retrieve a search results page.
Basically, my website will compare different electricty rates, and therefore the user must enter their info in order to get the corresponding suggested electricity rates. I thought I would be able to use GravityForms but I am not sure it does.
Anyone has any ideas on how to do this??
Thanks for your help!!
