The amount that anyone can get away with charging is directly dependent on the local market's accepted amount.
Even here in southern Manitoba, I have to change my quotations depending on location. If bidding outside of Brandon, population of around 40k, I have to lower my rates to stay competitive. Whereas within city limits, which has more competition, I can get closer to what the job's worth.
If you over-price your work ........ word will spread quick enough ......... and it will come back and bit you in the backside! PHC allows certified individuals and those with excellent reputations the ability to charge more than their competition, but when dealing with removals, it's a touchy area!
The tree you showed .............. I would have taken it out, cleaned up, and hauled away for probably $450 ............. keeping in mind we are all looking at a picture. Then probably another $50 to 75 for stump grinding. I'd probably be slapped in the face if I told the homeowner that it was going to cost $1000+. But all the more power to those who can...........
