Should I do it?

I'm looking for ways to get just little bit more oil and I thought about posting this on CL. What do you think? What can go wrong??
Hello fellow greasers. Are you tired of replacing filters in your set-up or cleaning up the messes? Let’s work together. I have a state-of-the-art centrifuge that has more capacity than I need now. For those that don’t know, the centrifuge is the filtering method of choice since it filters and dewaters in one pass. I filter at a very slow 2-3 gallons per hour, as opposed to the 10-12 gallons per hour the manufacturer recommends.
Here’s what I propose. You bring me WVO and you’ll leave with filtered oil right away, no waiting. My fee? 20% of the oil I filter. So, you bring me 10 gallons, you’ll take 8 home and I’ll keep2 gallons for my trouble. It’s that simple. The oil needs to be free of water and fossile-based oils (motor, hydraulic, machine, etc.), basically WVO only. 

I'd meet folks in locations other than my house so my wife feels safe. I suppose I could get a bunch of crap oil that I have to dispose of and I've just given away oil for free. Any input is appreciated...
