Your team should have a very good developer proficient with GIT / Laravel / MySQL. Please note that I have no knowledge of the legalities involved and I also desire a complete understanding of the project by the development team before we begin the project to avoid any additional points that I may have missed. Project needs to be responsive for mobile and code should be scalable for atleast the next 3 years. Please let me know if you need to look at the frontend of the website.
