Build Facebook connector app -- 2

I need someone who is familiar in creating Facebook app and has strong skill in Python (Flask)

Someone who can help me to build a connector in within existing python(Flask) app between facebook and a CRM. The connector lets you sign into a FB account and select the lead ad then takes data from the lead ad and insert into CRM. The fields are mapped between lead ad fields and fields in CRM so right value from lead ad goes into right field in CRM.

I'll provide the API details of the CRM
