Hi, I'm still waiting for my MD Home Improvement License......... So while the magic number comes I decided to, at least, start installing gravel driveways and similar application that does not need License in Maryland... My question is... what is the average price per SF of this kind of work? And how it is best to apply it, for example, on a driveway? (how deep to excavate, only take vegetation out, etc...) I know that ESTIMATES DEPENDS ON SEVERAL FACTORS!!! And can never be done by square footage. But I have completely no clue about this, and I would like some rates to try to get an idea. Once again, this is for Maryland. As always... Thank you for the help!! Kat PS: Any tips or help in this matter will be greatly appreciated.
