Sandblasting?

[Alex Carlson]

Anybody know of a good (i.e.: cheap) shop for sandblasting?  I'm trying to finish up my big block Ford motor, and I need to get the oil pan down to metal to repaint it.  We've got a hand-me-down blast cabinet in the shop, but it's barely big enough for the pan, and it's really an exercise in futility.

Any suggestions?
