3D Printer Tuning Services?

I picked up a Prusa i3-style printer a while back, but had some trouble setting it up, then set it aside and never got back to it. While I’ve been meaning to fiddle with it to get it working, I think it might be good to just have someone who knows what they’re doing take a look. Besides likely putting it together not quite right, I suspect one of the main rods is a little less than straight… but it might just need tuning and bed leveling.

Anyone available for this sort of thing?
