WP developer needed to fix Multi-site domain mapping issue

Overview

I’ve setup a WP Multi-site and its working but when I try to map it to Custom domains, it doesn’t work. I need a WP expert who can log in using TeamViewer and fix the issue.  I will not be able to give login credentials. Should take less than an hour for an expert.  Please send a flat-rate quote (Will not pay by the hour)
