An Alternate Source for Dairy?

I'm going to try and make an effort to find a dairy cow producer that will sell me raw milk on a semi-regular basis. Or perhaps I will be able to find someone that would be willing to sell me a part share in a dairy cow (Jersey would be good). I want the milk, but I also want butter and maybe cheese. Butter is the biggest part, I can't make butter from what is sold at the local grocer's, it's been homogenized to keep the cream from rising to the top. Good for drinking, bad for making butter. Right now, butter is the single most expensive item that our family uses regularly. While I'd love to have a couple of goats again, I run into the same problem I did 10 years ago. I have nowhere to keep them close-by so they could be milked twice daily. Though I really do enjoy goat milk. It's just not as easy to make butter with goat milk as with cow.
