Batchbook specialist: posting data from Joomla/OSE

We have an existing Joomla based website using the OSE Membership plugin. The existing [login to view URL] script has already been amended to post registrants' data to: 1. Another mysql database on a separate domain on our server 2. ActiveCampaign (our autoresponder, also on our server). The script now needs to be amended further to post same registration data to Batchbook (online CRM). Fields have already been created in both our sql and Batchbook databases. We are looking for a php/html programmer who has used and is up-to-speed with Batchbook, as well as Joomla and OSE to complete the coding and testing. This is required ASAP as our website needs to go live.
