Bug Fix for a Direct Payment Integration

We had someone to make a Direct Payment Integration (CardSave Payment) on our website www.bestavsystems.co.uk. Because does not work as should do, we do not want to come back to the original developer, as we do not trust them any longer. We know what the problem is but we want somebody capable to sort it out. No more messing around. What needs to be done: [login to view URL] issue with 3D secure and the system is to an incorrect formatted variable being passed to the banks 3D secure page. Whilst the CardSave 3d secure simulator is not case sensitive, the banks systems are. The post variable the website is sending: PaREQ However, this should be (notice the case of the letters): PaReq 2. When processing a card without 3d secure, the website does not redirect to a page on the website where will show what you bought or to say that the transaction has been completed. Just stay on the same page from where you can press the button to make payment on and on. Somebody with experience in payment integration knows exactly what I am saying. PLEASE, only serious workers. Do not bid if you can not do it or if you do not have time only in 2 weeks to do it.
