Hmmmm. It's a reasonable question but I'm not sure if I'm comfortable putting it here. Drop me an e-mail and I can give some numbers though.
(Because my rate varies based on a number of factors and this is effectively an advert, I don't want to anchor any buyers incorrectly in either direction.
Too expensive: I don't want to say 2X and have companies with a budget of X and an interesting job rule me out, as I might do X for the right job.
Too cheap: I don't want to say Y and have companies with a 2Y budget either get me for cheap or reject me because they infer I'm not good enough.
And if you're looking for someone to hire, look, I can do commercial thinking as well as programming and I've given away that I'll give you a discount for an interesting project. Drop me an e-mail with what you need and I'll give you a price.)
