WHMCS split signup form into multiple pages

We require someone to create pagination of the WHMCS sign-up script adding separating the default processes onto separate pages and group specific options we require the Product Configuration, Product Options and Product Add-ons sections to be loaded on separate pages during the sign-up process This should be a quick simple process for any competent php programmer Coding must be to a level of standard that is compliant with WHMCS 4.2.x and will need to work within our existing sign-up template style which is based on the web20cart template that whmcs comes with **Just to clarify the work required.** We require the Product Configuration, Product Options and Product Add-ons sections to be loaded on separate pages during the sign-up process instead of on one single page. The code needs to have the normal Continue button included at the bottom of each page I would also like some code added to the Product Addons page thats created that will allow us to group specific Product Addons together and with a sort order function rather than the random load they currently have as an example of what i mean go to [login to view URL] and order a server package by entering a domain name and clicking on the Click to Continue button You will see the various sections that need seperating Under the Addons section you will see there are SSL certificates, Dedicated IP's, Software etc I would like a function written into that page which will allow us to create a group of Addons, and then under that group specify which addons are displayed under that heading I have mocked up an example of the addon page at [login to view URL] as you can see ive added a Step 1 - 2 - 3 - 4 - 5 fuction to show the client where they are at. The design of this im not too woried about but i do requie the functionality to work into the breadcrumb function so the client can go back over any existing steps by clicking on the step number.
