For a couple of years, back in 2008-2009, I had a freelance support gig with a former employer who I'd built a system for when I was a permie. We didn't have any real solid agreement on my availability, and the deal was for £100 a week, paid 4 times a year. I'd moved on to contracting, so I had to juggle my new full-time work with the support phone calls. I'd stick with keeping it separate, rather than the higher hourly wage. I'd also try and put a limit on the amount they can contact you (perhaps a maximum number of hours per day), as I had occasions when for weeks I'd have no phone calls, and then on one day spend 6-7 hours on the phone to them.
