Calculator for Website Prices

I want to add a calculator to my site. When someone visits the page with the calculator on it, they can choose all of the components I add to it. Each component will have its own specific price. The prices will show, and a total price will only show as soon as they hit the Calculate Your Total button. *That way it will send as an email before showing they're total* I will also need a built in price for Paypal fee's, etc. This has to be EASILY customizable for me. I need to be able to add/delete/edit anything easily. It needs to go straight to my email whenever someone fills out the form, and hits the button to get the total. The entire contents of the form will be sent to me, inlcuding the total price given at the end. Please make FAIR bids on this, as I have a very limited budget. MAXIMUM OF $40 This will be used on Multiple pages, *Website Design, Logo Design, Graphic Design, Print Design* and the content will be different for each. -------------------- I am a Website Designer, so If you would be willing to do programming work *more than just this* in exchange for website design, that would be great as well...
