This is the kind of thing I'd really love to do and I think I'd make a good job of it too. Much easier to work on stuff you are interested in.
Thing is, I'm absolutely up to my eyeballs in already booked work. I worked this weekend, I'm working evenings, I took very little holiday over Christmas and yet it was still more holiday than I've had on months - things are, in fact, getting out of hand. I'd promised myself that I wouldn't take on anything new till at least my 2 biggest existing projects were done and live.
This one was recommended by a satisfied client, so I kind of don't want to disappoint the client, and I really fancy doing the job. But... Arg!
