Build a website that calls a remote API and displays results. - repost

We have an asterisk based switch, with full API that is ready built. We need a website to have some simple buttons, to call the remote server API and display the results. This will be an ongoing development - just now need simple information displays - nothing fancy, very basic, first steps, read only.. Basically JSON authentication, API keys, all need to be hidden, and just now, a few simple buttons and forms. securing site to a login by username and password, for admin view (can be simple at this stage and develop ongoing) then simple client(s) views of Calling statistics, showing DID´s, and showing live channels. Ongoing part of project - will be sending write commands, enahncing looks, functionality etc.. adding looks, have some comparisms available.. this project is suitable for those with Asterisk API and PHP knowledge please estimate rough hours or project costs - ongoing development - we have a lot to evolve, this is only the start, please view this initial start as a skill demo, (we will need much more in the ongoing stages, rolling, CRM development, functionality, graphics, refinement etc - probably 1-2 days a week ongoing as we will add things in small phases) rgds David
