Looking for large animal bones, preferably cleaned. Any animal is fine, cheaper the better since we'll be using a lot of them.

Terminally ill husband wants to build a dinosaur skeleton in the front yard to...er...delight the neighbors. We need a large number of big animal bones for this project. I will be doing most of the work and have no idea what I am doing, so advice is also welcome. But mostly we need the bones, the bigger the better. Long bones and vertebra, ribs, knee, one skull... I would obviously prefer cleaned bones but can also learn to clean them myself if necessary.
