here's one who's a well known and popular these day...may be a little price being that he needs to repay $2k in taxes for being unlicensed all these years...
ohh yea, his names Joe!
seriously tho, before setting out to find someone...bathroom upgrades is not brain surgery. if you can tool around with your car..installing a new tub is a peice of cake.
look into some DIY's, it'll save mucho dinero...can prolly donate to the help Joe the Plumber tax fund
