Customization of SuiteCRM

We would like to customize the implementation of SuiteCRM for our organization - Quality Kiosk that is based in Navi Mumbai. The implementation is already live and features that would need to be added are: • Field level visibility depending on User Roles • Multiple assigned users for Opportunities and Accounts • Assign Create permissions. With this ONLY SALES HEADS can create accounts/opportunities. • Autogeneration of AccountID, Opportunity ID and Opportunity Name. • Customization of reports • Notification on change of opportunity status Workflows for approvals of Quotations and proposals. The freelancer needs to be based in Mumbai or Navi Mumbai and meet with the organization prior to the start of the project.
