PayPal and customer enter price

[fentontech]

I cant seem to find anything on this at all and I know it cant be impossible.....

All I want to do is have a product called "Payment" and let the customer enter the Price and then pass it to a PayPal Module (doesnt matter, which ever is best recommended).

or is there a way to easily have a selector that shows $1 to $3000?

I would prefer the solution where the user can enter his price.

is there an extension that can do this? even if I have to pay for it?
