By the way, I DO start with a basic formula and then adjust from there based on other factors. $/hourly rate x hours required plus $standard trip charge. Then adjust from there. I think ultimately the bigger you are and the more strangers you have doing the bidding and the work the more formalized you need to be with it. But the ultimate test is do your bids match the reality of the time it's taking to do the work? I always get my goal price per unit of work done and often better. I do not like working for peanuts. Another factor I forgot was "convenience". For example, is the property on the way home at the end of the day from others where you can work later w/o hitting traffic? I wouldn't be working in some areas of town at 4:30, since I'd get stuck in traffic and waste tons of time sitting in the truck. But if a job was further towards where I live, I could be working at 6pm. So that lawn might be worth discounting a little.
