I have a sign up form (through Google docs) that allows music artists to sign up for services. At current time I send an invoice to the artist after they submit the form. What I am looking for is:
My current sign up form to to be integrated with a payment system so that as the artist makes selections, the price will be calculated and when the form is complete they would pay immediately and submit the form with payment.
Would also like to allow for the attachment of the artist's Music and Audio.
