Irrigation system winterizing question (money, mechanic, sprinkler)

[geoff2v]

Hey folks:

I have a sprinkler system that needs to be winterized; I possibly could figure out how to do it in future years, but I'm really not mechanically inclined, so I'm going to need someone to do it for me this year, at least. I'll watch what he or she does, in hopes that I can do it myself next year.

So my questions:

1) Any recommendations for someone who will winterize it, for a reasonable amount of money?

2) The low is supposed to be in the mid 20's next week, and the pipes don't go down very far. It'll get back into the 50's during the day. Should I be worried that the pipes might freeze? I wouldn't think so, given the short length of the freeze, but I really don't know.

Thanks!
