I needed one in my ls/vtec awhile ago, which I thought was going to be pretty hard, I got a helms manual, valve tappet feeler guages, and went outside to do it myself, and it turns out it was just as easy as any single cam or LS I've ever done, only took about 20 minutes too.. I suggest just grab a helms and do it urself, save some money and learn how to do it for the next time u need it done. Keep in mind the car has to be cold though, good luck!
