Simple integration between SugarCRM and WHMCS

I know well about WHMCS development but almost nothing of SugarCRM devel. The idea is to integrate in a simply manner SugarCRM and WHMCS on the Sales side. 1. Integrate SugarCRM Opportunities with WHMCS Quotes - WHMCS quotes byself is not great but can be a good tool integrated in the following manner: - From SugarCRM Opportunity the sales guy may create one or more quotes - Via WHMCS API (which is pretty easy), we should create a new quote to later be filled and concluded via WHMCS - it would be expensive and complex to integrate all the functionality of the WHMCS quotes screen into Sugar. I mean because of the products and it's variants. Via the API we should at least create subject, validuntil and some other simple text fields. - [login to view URL]:Create_Quote - So then will exist links on the opportunity to all quotes related. That will take to WHMCS [login to view URL] screen. And the sales guy will be able to edit and add products etc. - We should have the possibility to associate previously generated quotes on WHMCS to current opportunities in some way (by the quote ID, exactly as the new ones will be related). - It would be amazing if the user from Sugar be automatically logged in into WHMCS so then when it tries to edit the quote on WHMCS it will not be asked for the login information. - It would be really amazing if we could save the quote`s PDF into SugarCRM documents (get the PDF from WHMCS is easy) - I would like to have all the source code. I can help on the WHMCS side. 2. Configure KReports to show at least the documented reports on it`s SugarForge page.
