I need Perfex CRM modifications

I am looking for a developer to make modifications to my Perfex CRM as per Indian GST Requirements. Specifically, I require custom modules to be implemented. I have a detailed list of the modules that I need, so the ideal candidate would have experience with Perfex CRM and be able to work with my specifications. The deadline for this project is flexible, with a timeframe of one month or more.

Here I'm attaching a detail doc of requirement
