Processor gave us a payment module for zen cart, but seems it does not collect all the info correctly on our site before redirecting for payment. So your job is to fix any programming issues in the module or on our site to make this payment module work. Should not be such a hard job as the payment module for zen cart was already given. Coder must have very good .php skills and preferably previous payment module development/integration experience.
Have attached zip that includes the module and integration manual.
