A guy I know has a brother who works for one of the local rendering outfits. Talked to him about buying WVO from them direct. They'll sell it to me for a reasonable price - well under a buck a gallon IIRC. The catch is I'd have to buy a whole truck load at a time - about 4500 gallons.

Now, if I could just round up about 10 local people who all wanted to run WVO and/or make their own BIO, and who each have the ability to haul away 500 gallons, we could split the cost and everbody would get some oil for a reasonable price - without having to invest the time and money collecting it.
