Yep id want £350+ per day for contract dev work and as I woudl have to do this after hours or at weekends thats time and 3/4 so £600 per day x 5 thats 3 Grand for a week.
Oh and £350 is low for a day rate you can easily get £500 plus for high end devs in the city / big data.
I would absolutely charge for this kind of thing, but like I've said before, if I was looking for contract work, I'd be a freelancer. I'm not looking for a one-week contract with a possible extension, I'm looking for a full-time job. For Jeff to offer me a one-week contract as an "audition" completely misses the point of my goals in favor of his goals.
But yes, if you wanted me to work on something for a week, I'd absolutely want to be compensated for it. But in my current situation, I just personally wouldn't take that offer.
