Where and how expensive to have ornamental yard table and chairs sand blasted?

I would use a wire wheel to knock the existing paint/rust off. Id imagine it would be $$$ to get them sand blasted.

I have a sand blasting cabinet for smaller stuff but use the sand blasting pressurized tank outside in the driveway or on the grass. I really like seeing the results and comparing to the pre blasting condition. Yoogly to beautiful with just a bit of work and sweating inside the hood and coveralls.
