148335 Online Payment Processing

We need our auction site using PHPPROBID script to be linked to our online payment processor/merchant account so that we can accept and process credit cards online. This is a pretty straight forward task which would require building order forms and linking to these forms to the payment gateway and restore the returning data and values to the database. Please note that we do not have much documentation provided by the bank therefore we would prefer working with programmers who have done similar or same tasks before in the past. This is an online processing / merchant account obtained by a local bank. They are using a new system called 3d secure which requires the buyer to enter credit card pin numbers before authorizing a transaction. This is an urgent project and need to be completed within 24-48 hrs.
