Hey everyone, its been awhile since I've been on here, I know you've all missed me

Anyways, I'm posting because I lost a rewall project, of good size, to someone who has way under bid me. It happens to everyone and to myself, but when its a good friends family who does it, it's frustrating.
Heres the project in a nutshell: Total square footage: 435 (on the conservative side). Approx. 170 linear feet of wall. Block of choice is Anchor Highland Stone w/jumpers. Front yard and driveway project, so easy access. No room for storage of spoils and/or gravel. A lot of excavation (approx. 5-7 truck loads). Existing limestone wall needs to be removed. It is you typical middle class home with the driveway cut into a hill and walls on each side (one side having 2 tiers) and a wall running along a sidewalk acrose the front of the home. The other wall on the driveway wants to be pushed back about 2' to fit trash cans in. Wall to be capped.
Thats a quick description, i can get more exact details if needed, but I'm really interested in seeing a few figures to see how i fell in among you guys. I found out what he was charging, approx. sq. footage price, and i figured out where I was at with square footage. Thanks for any and all help on this guys. I'm kinda frustrated right now because I've gone and changed the way I'm estimating because I'm tired of short changing myself and coming in lower than everyone else. I'm curious now if I'm coming in too high compared with everyone else.
Again, thanks guys and I'm looking forward to seeing how everything compares.
p.s. The big kicker is this guys price (per sq. footage) also includes landscaping, how extensive it is i don't know, but you'll be surpised by the price.
