Here is what I need: [url removed, login to view] (of course this form is totally messed up, I want something better)
When people fills that form and click the button, a value will be showed, so the user will know exactly how much he/she will have to pay.
I'll provide the values.
Doing a admin area (so values can be easily change) will be awesome, but is not needed (you'll just need to tell me how can I do that)
As Simple As That to be done As Soon As Possible
