This is a problem for quite a few people I believe, myself included. Unfortunately Pulping and hulling are 2 different machines, generally due to pulping being a wet(ter) process and hulling dry, or so its been explained by a the sales guy when I suggested a dual usage machine. Some people use an old kitchen whizz type affair with a plastic blade for hulling, and I have used an adapted old style meat grinder. There is an Ozzie company that sells hand pulpers which are not tooooo expensive ($200-$300), although probably not cost effective for the amount of beans you are talking currently. Its Cape Australia (non sponsor).
Pulping is a different matter, as it need to be done soon after picking etc. I could not find a hand pulper in Oz, (although it looks like Cape may have one now), and considered importing one from India/China. But once again you are talking $500-$700 or more landed and really not cost effective for my amount of beans. I did suggest once if I imported one then leased it out for a while to help defray the costs, but I got no takers, so assumed there was no demand and have not progressed that as yet.
Someone mentioned a farmer near/in Mt Tamborine in the Gold Coast hinterland (NOT Kees from MTCP, but a small farmer) who may be willing to help, but not sure who they are. You do not indicate where you are based.
