Order form template request

Hello,

We are looking for someone that can build more intuitive process for ordering Dedicated Servers from our company through our WHMCS shopping cart.

We need something similar of what Singlehop has currently at, https://www.singlehop.com/order/form#page1.

Customers will have the option to choose:

Datacenter
CPU
Hard disks
Disk controller
Memory
IPs included
Port speed

Next page would have the following,

Operational system available
Version (architeture)
Control panel options

Next page,

Backup services
Monitoring

Next page,

Payment info

- I need a web panel to set up each of the available products for ordering, and which of them are compatible to what amount of disks, RAM, por speed, etc. I know that I can do this from WHMCS, but I am not sure if you will be able to build such order form without an external control panel. Either options would do the deal.
- I also need different fields for Brazilian customers (when the page is set to Portuguese) and for foreign customers (when the page is set to English), because there are some fields on our current order form that needed to be removed from foreign customers (like CPF and CNPJ).
- I also need different payment types for Brazilian customers and for foreign customers, because there is one specific offline payment method for Brazilians that doesnt apply to foreign customers.
- There are many fields on our current WHMCS shopping cart that remains in Portuguese even when the page is set to English.

Our current order form can be seen at https://portal.maxihost.com.br/cart.php?a=add&pid=451

Thank you very much !
