Looking for a web developer to help me doing a market research on LMS platform

I am looking for a web developer to help me find the best online building course platform that supports:
-LTI link
-Membership options
-Website
-Application android
-Downloadable documents
-Videos, images content

I am open to working with two different platforms:
-One with learning content and membership for B2C
-One with LTI link for B2B who already have their own LMS and will integrate my learning content
