If you're driving out that far, either you or the HO is losing money. 3 hrs of commute is 3hrs x your hourly rate (let's say $50)= $150 of lost time. Gas, kms, now you're closer to $175. A $300 job becomes $475. OR a $300 job becomes $125, cut it however you like.
I stay within a 30 min. MAX commute time, each way. That's MY limit. I'll eat that cost.
If somebody calls me for a quote outside of that range, I either refer them to a buddy GC/trades guy, or tell them straight up that I'm charging for my time to-and-from.
Count your bottom line, "if it don't make dollars it don't make sense (cents)"!:thumbup:
