We are a team of web designers and developers with 800+ sites for varied business profiles to our credit. We have expertise and experience in PHP and MySql. We have developed many custom sites of varied kinds and of varying extents and complexity. We have also designed and developed an online course booking site for language courses but client has not gone live with it.
I have read your requirements and I am confident of delivering well. We have delivered sites based on similar concepts (profit sharing, online booking, admins to manage their own sections, search by proximity etc,). I just request for detailed specifications so that I can assess scope of work more precisely and revise or confirm my bid accordingly. Please check PMB.
