Require addon for WHMCS for Lastschriften/DTA - german payment method

[highfly]

hello,

 

we are lookign for someone who can develop the following for us.

 

We sent out our invoices on a monthly basis. some of these invoices will be payed by "lastschriftverfahren". therefore we need a file called "dta-file" which we can download and process it with our bank.

 

requirements:

-client data needs to have the following details: account owner name, bank name, account number, bank number and a checkbox "Zahlung per Lastschrift"

-these values should be changeable in the customer interface as well

-if an invoice is generated for a customer with "lastschriftverfahren" it should be shown on an extra list within WHMCS with checkboxes to mark them as paid at a later stage

-after the monthly generation of the invoices all invoices marked with "lastschriftverfahren" should be combined into a dta-file (which includes informations of our bank account and the customers bank details, invoice number, invoice sum, etc)

 

is there anyone able to give us a rough price estimation for developing such an module?

 

regards
