manure for composting (Cambridge (West Galt))

I'm a backyard gardener looking for a local supply of manure or animal bedding (straw / manure mix) for my garden composting project. Manure can be from horses, sheep, goats, cows. The ideal is relatively fresh manure which I hope to compost over the growing season. I'm happy to do the shovelling myself; I've got all the bins and shovels I'll need.
