Looking for a simple form plugin that does

I’ve tried a few but looking for a light weight plugin the does the following. The ones I have tried have too many options so I am looking for something basic.

1) User visits home page and sees a form.

2) Fills out the following data. (we log users)

-First Last Name
-Email Address

3) Presses submit.

4) System automatically emails a message to the email provided and sends off info they requested.
