I see you were looking for somewhere in Citrus county for hydrotesting.
Just wanted to drop you a note that I test paintball cyl's in Homosassa FL.
They can be dropped at my shop or if you are out in Ocala at Waynes World I do a weekly pick up usually on Wed from them. I also pick up at Scuba shops in Fort White, Williston & High Springs area every Wed for folks up that way.
