Sherman's not really doing refins anymore, he's got plenty of other stuff on his plate.
Sims does a great job, but he might take a while (his shop appears to be quite busy on the paint front).
I don't think you want to deal with ET for that cheap of a guitar, as they're based in Australia and shipping would destroy you.
I'd get a quote and a time frame from Sims personally, but I'd also check around local stores. For that cheap though it might well be good to do it yourself! Just be ready for a LOT of sanding.
