We are looking for a someone to develop a completely custom WHMCS checkout page based on our requirements; developer will need to utilize the WHMCS API: http://wiki.whmcs.com/API
The checkout process needs to be secure and needs to be compatible with two gateway API's and version 4.1.2 of WHMCS. This is very important. We would also like to limit the checkout process into two steps, one step requesting information and one step for payment. Someone who has prior experience is most certainly preferred as this maybe a bit difficult.
Finally, we won't be able to provide you with access to the WHMCS software for security reasons. We expect the bidder to have access to this software and to be able to test this on his/her own server before submitting the final product.
If you have any questions, please ask.
