Looking for someone who has experience with Access Points to be sent over and fix an ongoing issue

The current issue is that one of my clients has 14 access points, but 1 of them specifically is dropping out for up to 8 hours at a time. I have a budget of $1,500 , but if needs to I'm willing to provide more funding.

Hoping to find someone asap, ideally within this week to take care of it.
