Well, I can help you do it yourself.
I am going to put my two barrel Lortone tumbler up for sale on eBay this weekend unless a Guild member wants it. In addition to the two barrels I also have two custom made long tumbling barrels I used to use for pens.
I am just not a production person. If you are this can be a great help. Drop me a line at firstname.lastname@example.org and make me an offer, and I can bring this to the meeting.
