I will need to add to the payment system in an WordPress Daily Deal site. At present there is only one option is to pay now and then a voucher and receipt is sent to customer. We need to install a installment payment function in this system So I will need 3 options - Pay Now, Pay Weekly Pay Monthly. In simple terms if we choose to offer 2 alternative payment terms We need to fix the initial payment the number of subsequent payments and the frequency of the payments. Payment every 7 days and payment monthly Example: $245 Holiday for 2. Pay Now $245 Pay Weekly Initial $45 the 4 x $50 payments. Pay monthly : Initial $45 and the 2 x $100 payments. The system will have to be able to let me enter all these variables in for each deal. The new system will take the fist payment and get authority from PayPal for the subsequent payments. After each payment the customer will be sent an email as a receipt and to let them know how many payments are left. Let me know if you need more explanation. Unsure what price to expect please just quote what you believe is the right price for you. Enclosed is a spreadsheet showing what I want. Plus the reporting side. I also can give you access to the website and the admin area. Just ask. Thanks
