Learning Management System -- 2

Hi, I want to develop a LMS to sell our courses. Clients should be able to register as individual or a business pay for our courses online and be able to if they register as a business be able to develop their courses using a basic course builder. I would also like businesses to register and register their staff (by single entry form or upload .csv file) and do courses on our system. Basically just like talentlms / iSpring Learn
