dwolla payment plugin for wordpress

I have a wordpress site and want to be able to accept payments via dwolla I need you to develop a plugin that I can embed on a page of my site that prompts the user to enter 2 pieces of data (invoice number and invoice date). The date should be populated/validated with HTML5 datepicker and the data entered will be compared with an existing table in the MySQL database. The database will already have the following fields: CustomerId CustomerName InvoiceNumber InvoiceDate InvoiceAmount InvoiceNotes InvoiceStatus InvoicePaidDate DwollaResponseCodes If the invoice number and date do not match an entry, the program will display a message that the record was not found and to contact their representative. If the invoice number and date do match a record, then the program will display the Customer Name, Invoice Number, Amount, and Notes (if notes is not blank), followed by a PAY NOW WITH ACH button that will kick off the Dwolla integration. It is helpful to have an additional table in the MySql database to keep track of the unique token assigned to each CustomerId but I will leave the design of that table to you. Customers will come back multiple times to pay additional invoices, so storing their verified information is necessary so that future transactions can happen quickly and easily without reverification. When the dwolla transaction occurs, the status should be saved (either paid, unpaid, or pending) to the InvoiceStatus field, and the log data from Dwolla should be saved to the DwollaResponseCodes field for future troubleshooting. If other fields would be helpful (such as token id, etc), that can be added. Because ACH transfers can take up to 3 days to clear, there must be an admin interface that has the following features: -- A "verify/update" button to check with dwolla regarding any "pending" payments to get current/final status -- An interface showing all current Invoices and their status (unpaid, pending, or paid) -- A basic form allowing admin to add a new invoice record to the database (most of the time, these records will be generated from another system, but it is nice to have a manual entry for testing or occasional one-off charges) Information about the API is available here: [login to view URL] I suggest that you will want to create your own sandbox account for testing, and I will do likewise once the project is ready to turn over.
