Opinion without supporting reasons is like a mouth w/o teeth, imo. Let's hear them. I use Ebay/Craigslist, like many, for selling items with good success, but I've been blessed that it's been all word of mouth for services for 25+ years. Don't have personal experience with Angie's list, but just about everyone that I know who are users have nothing but good to say about them. Last time I spoke with one of the tree guys I know spent around $15k with them this year. He wouldn't spend that kind of money unless it had good returns. What specifically are you looking to do? Willing to travel to the Columbia/Howard County area? I referred over a half-million dollars of work last year to people I know that do very reputable work.
