How about using the “Marshall $ Swift Home Repair and Remodeling Cost Guide”. Sells for about $30 and available from Amazon and others.
This is updated every year or 2. It gives breakdowns of most typical repair/remodel projects, including labor, and in the back of the book is a table to adjust by geographic area by ZIP code.
Drywall, economy quality, small room (48-80 sq ft)
$400. Zipcode 582xx multiply by .86 Estimated cost $344.
Get your money, then find someone who will do it for less.
Hope this helps.
