Babysitting Exchange

I've seen a sign up go around for this, but I'd like to see if anyone would like to exchange a specific day/time.

We hired a babysitter yesterday afternoon and realized we definitely cannot afford that on a regular basis! Teenage help is not cheap! So we were wondering if there is anyone out there who would like to exchange babysitting on Saturday afternoons (or mornings or evenings if they are better for you). We would like to go out from like 2 or 3 in the afternoon till 5 or 6 in the evening. This way it doesn't involve naps, baths, bed or dinner (maybe just a snack). We've been exchanging babysitting with the Gunns at night, but we would really like to get away from our kids when they are actually awake and when it's early enough to go out to eat or see a movie or even go to the temple.
We'd want to exchange once or twice a month. Which means that either we both go out once a month or we each go out every other month. I don't know what other peoples' Saturdays are usually like, but for me Roy usually works all day, so having a couple of extra kids over to play would be no big deal.

We will be moving in June or July, so this would be a short term thing. And if you decide it's not working out, we can stop at anytime. Anyone interested? If not, no problem, we'll hire some bum off the street to save money ;)
