Data Integration between SQL Server and Web Services API

We need someone to create an application that connects SQL Server databases to an external email platform API web services (HTTP). Basically we need to send data (one SQL query with email address) on a daily basis to an FTP website and thereafter push the data into the external email platform in order to send an automated email. We also need to extract data (again one query) from the external email platform and insert it back into a specific SQL Server database for analysis purposes. The external email platform is Communicator ([login to view URL]). The FTP website will be hosted by Communicator. Communicator integration documentation is attached with links to example of HTTP POST, HTTP GET and SOAP scripts. Please let me know if more details are needed.
