Customer Application form

Hi,

I would like to get input on the best way to make this happen, i need to create an application form that has about 25 fields. When the user fills this out and hits submit, i would like all those fields to be either sent in the email or a .txt? But i’m not sure how to proceed.

If there is a general direction i can be pointed at by someone who has done this that would be greatly appreciated.

Thank you!
