Pig to pork

I have the opportunity to "split" a pig with a neighbor. He has raised it, but it's gotten just plain mean, so has to go.
Neither of us has ever done this before. There is a processor that all his friends use,so we'll go there, but beyond that, we're clueless.
Anyone know of a website or source to learn what we should expect? Or do or say? Or even what questions to ask?
We have charts that say how to estimate the weight, but that doesn't explain what we will end up with. I hate to go into this without some idea of what we will have in the freezer.
Any thoughts?
Thanks
Margo
