Head Tube Help!

Here is the Frame hope they satisfy its gonna need a fair deal of work, Does anyone know a place where i can get it sandblasted cheaply, as there is some rust that needs to be got rid of and the paint aint in good nick. Thanks>
hmm dont seem to be able to upload any photos any help?

I can get access to a bead/sandblaster after the new year if you can wait that long, it uses fine beads so it takes a while to strip everything, but wont damage the tubes. I'm not up on what and how to mask though.
