Add Saas template to a CRM application

Th goal is intgerate two scripts (Taskgo and Perfex project management) to create a Sass software. Perfex is a project management software and Taskgo is a template that have alreday the Saas logic. I have Perfex, i must buy Taskgo. Alternative it is possible create the features of Saas logiic from scratch. I attach the link to 2 scripts (plese study them): - [login to view URL] - [login to view URL] Pratically now Perfex isn't a Sas software, so it is necessary integrate with Taskgo. In this way the clients that buy one plan can use the software Perfex and see only your informations. It is necessary also the plans and the clients are integrate with Perfex regard the autorizzations to see or not same pages. So the activities are: - 1.1 integrate the plans with the authorizations (too see or not the page). So practically when the administrator decide the plan can decide also the page that that plan can have; that have Perfex (to see the pages (every plan have some page that the user can see or not). 1.2 integrate the client that bought a plan with Perfex to have the correct navigation with Saas logic. And it is necessary delate all feature of Tskgo that have already Perfex 1.3 integrate the Perfex authorization page with clients to create a personalized authorizations for clients. In this way it is possible give specific authorization to see some page to a specific client 1.4 add some field to registration inside Taskgo Conditions: I reserrach a person expert in Saas (it must demostrate that made Saas software otherwise I can't asign the job).Max budget: 40$. deadline: 2 days
