I haven't done that exact mod, but have priced ballast for my boat several times. It tend to average out to somewhere in the $300 to $400 per sac once you buy all the stuff.

Take a look at the below post or do a search for GI to GIII and you will find some more posts. The ruff costs is around $800 or so plus bags. This does not include the beer fund.
