Need some help with some PHP coding, contact form + database info Options

[maxaud]

Hey guys, I need some assitance in writing some PHP coding.
I'm getting pretty confused as to how to do it as I'm not very good at PHP let alone connecting to database info.

Here is what I want to do:

I enter in email address's into a database table which are connected to certain ID numbers

Someone goes to a domain like...
http://www.fakedomain.com/contactform.php?id=20

When they go to that domain it looks up the ID # 20 from the database list and sends an email to it when the the form on contactform.php is submit'd.

So if I wanted to send the forms info to ID #4 for example the domain would be...
http://www.fakedomain.com/contactform.php?id=4

If possible, I would also like to display a unique picture that is different for each ID.

Anyone know how to do this?
Want to make some extra $$$?

Thanks!
