You probably haven't done much typing lately, and 70 WPM is not negotiable.
Hm. Quick question: Are alskga, wigjzxnv, pasovhwu, and lksjgshwnz words? Then I'm your guy! No extra charge, I might even make some of them cross. Well?
(Actually, I type pretty close to that with real words, too, but the whole "already gainfully employed writing software" thing and the "not living anywhere near your office" factor makes it seem a bit of a long shot.)
