Hi bet you can get tons of compost to be from a local horse farm. Check with local feed store as to how would be willing to help you. Maybe post a wanted and you may be surprized some one may be willing to even drop off to you.

Where to post "wanted" ad? At local newspaper? Thanks.

here is a link to a horse forum

maybe in the off course forum
or the give aways forum

post wanted manure in county//city/state etc

Local feed stores normally have a board up you can leave a note on, or enought folks will post they have stalls etc and thus manure .

I got great cheap mulch delivered from Jon at (908) 917-9221
