E-mail Setup for multiple domains

I'm looking for a simple email solution which will allow visitors to my sites fill out a contact form. Once filled out this will be forwarded to my gmail account.

Does anyone have any good/easy tutorials to do this? i'm new to linux and hosting my own server…

-or-

Is there anyone willing to set this up for me and document it so I have a guide to do it in the future (if I need to)? If so, please let me know what you would charge.

Thanks.
