Hello,
Hope you are doing well. Wish you a Very Happy 2015. I have reviewed the instructions on PDF, the process looked clear, however I could not check WHMCS Panel as it will require login credentials.
We have extensive experience in E-commerce and product upload tasks. We are one of the top notch service providers here and have a proven record of delivering top services.
if you could provide us access to WHMCS panel, then we can review it and quote you a fix cost.
Otherwise, we usually charge $5/hr.
If you have any queries, then please feel free to let me know.
Cheers
Ankur
