I know, right? I've lost track of all the money I've lost from clients going with the lowest bidder over the years. I must be literally hundreds of dollars by now.

A bit of advice: Those cheap guys are not your competition, and those bargain hunter clients are not the ones you're trying to land. Let them all race to the bottom all they want. Maybe one of them will find a dev who doesn't know his value yet, but the rest will get their money's worth. It doesn't concern you.

There is only one of you, and your rate is the same whether you're onsite in the Bay Area or working remote from anywhere else you choose to be.

That mindset has served me well over the years. I'd recommend taking it on board.
