Honestly I do it myself. At a shop it would just be a regular wheel truing. I think the last time I paid for one it was around $30. In Chicago I could see it being anywhere from $30-$50. If you are mechanically inclined and have some patience then you can learn how to do it yourself...even without a truing stand.

Hmmmm. It should be dished so it's centered in the frame. I've had to move rims over a half centimeter +/- and did it right on the bike. Loosen the spokes on one side by a half turn, then tighten the other side a half turn. Repeat until you're centered again. It takes some patience, but it's not that hard really. The more you tinker, the better you get at it.

I didn't have any problems. You asked about the re-dishing. The only thing a dish does is make sure the rim is trailing the center of the frame. You need to re-dish if your rim is not in the center of the frame.
Still can not make any sense of what your real problem is though, so I have no idea what you are trying to fix.

A bad chainline decreases pedaling efficiency and wears drivetrain parts at an accelerated rate .My front chainring and rear cog are not properly aligned on 2 bicycles.If I get this problem fixed I can have 1 bike with the capability to be fixed or freewheel with front and rear brakes.It will pedal more easily as well. I hope this explains it.Please feel free to "read" my other queries related to this subject.

Re-dishing the wheel (moving the alignment of the rim in relation to the hub) won't change the alignment of the chain and gears though. Are you sure you want to "re-dish" the wheel or adjust the position of the hub with spacers on the axle?

I guess I see what you mean now. You want to put spacers on the axle to align your gears, but that will throw the dish of the wheel off. That should be easy to do, just take your time.

As JW mentioned moving spacers is the only way you can move the chainline on the rear, and yes you would have to re-dish. None of that is very hard, but just freeking time consuming.
Thing is if you intend on using a flip-flop hub then the hub will need to be centered to be able to flip flop without needing to swap spacers and re-dish everytime you want to change bewteen the two.
Why don't you just swap out your BB to the correct chainline needed with the hub you are running? That's the usual, easy, and most effective approach to changing your chainline. New, correct length, BBs can be had for under $20 depending on spindle type. Much cheaper than a re-dish and spacers.
BTW - you don't need to explain the benfits of a good chainline to us...you simply have to state that you're trying to straighten your chainline, and wanting to change the position of the cog by adjusting spacers on the rear in order to achieve it.
