If you are asking to see what you would pay someone else to build your ARF, consider this:

Building an aircraft, even an ARF, requires some level of skill on the part of the builder to do it well enough to make a business of it. This would mean some level of experience building ARF's with at least a bit of talent.

A person doing this would charge a per-hour rate (even though they gave you a fixed price) based on the time estimated to build the ARF. Say it takes 10 hours to put it together. And, if the person is skilled, I would imagine that the per hour charge would hover around $30.00 per hour. SO, that charge would be $300.00 to put it together for you.

Is it worth that for you to pay someone else to build it for you?

Even at $20.00, you would pay $200.00 for that service.

One of our local hobby shops does building for others. He charges accordingly, and based on what I "quoted" above, and I would think that would be reasonable. You can't expect that person to work for less.
