Configure Azure Web Server

Hi I am having a bit of a senior moment and would like some assistance. I have an Azure account in which i have provisioned a Windows 2016 server and enabled FTP Access to it. I would like some assistance in setting up a service account, XAMP to run a PHP website I have had developed and ensure that it and the DB are correctly configured to run the code safely. I also need that person to connect the Domain I have to the VM with the webserver (1and1 to Azure VM). Should take an azure person no more than 20 mins to show me what I am obviously missing.
