Hi, first of all I live in WA. State I have been offered a 12 month commercial property contract but I still cant figure out how much to charge so here is the details. 1. The location is about half an hour away from where I live 2. Property is about 12 acres 3. Mowing (mulch), edge, trim, and blowing sidewalks required 4. The company who's taking care of that property right now takes up to 8 hours per mowing with 4 employees Please let me know if anyone has an idea of how much should I charge I do have a 61" and 48" scags, 48" walkers so I have the equipment ready to go its just that I always struggle with proposals because there's so much competition Thank you for looking.
