Create whmcs plugin

I need someone to create a whmcs plugin that implements the Voxbone api Retrieve Voxbone's coverage and price list Retrieve a full direct inward dialing (DID) list in an account Retrieve stock for a specific area Map numbers to capacity groups, channels and URIs Configure codecs and allowed services Retrieve a current account balance Purchase credits for Vox800 and VoxSMS Purchase or cancel numbers Purchase channels Retrieve Voxbone's POP list Check and track order status Download CDRs Manage regulation requirements As we will use it to let our customers search and buy a number some of the functions would be admin only [login to view URL] U should have your own whmcs server and voxbone test account I need someone that can work independently as has experience in jobs like this End goal: Customer can search available numbers, and order them. When ordered the default settings are used for Mapping numbers to capacity groups, channels and URIs Customer can add a port request (not possible via api yet so needs to be stored locally and admin must be notified for request) Admin has access to the other functions as well
