Honeydo listserve idea

Help me think this one through.  I'm thinking of starting another yahoo group or maybe a google group but this time it is to match people up who need something done but don't know who to call, or at least want to make it available to maybe a high school kid, or unemployed person looking to do a little work.  I might call it something like "Watauga HoneyDoers".  I don't really trust something like Craigslist for something like this...I would want this to be more local, or community oriented.

Recently,  I wanted to hire someone to locate and dig the hole to access my septic tank.  The septic company wants $100...well heck, there has to be someone willing to do it for less than that, some strong college kid, high school kid, etc.  But how do you find them? 

A friend tells me about the Job Board at ASU for students looking to do odd jobs.  I posted it, and got one response so far, but the kid charges $15/hour...a little more than I wanted to spend.  I offered $12. but why should college kids be the only ones getting in on the all the work?

So I'm wondering about creating a list.  Folks that are available to do side jobs, be it catering, construction, repairs of any sort could be on the list, and then homeowners and such could send an email to the group saying something like "Looking for one or two people to clean up the yard, rake leaves, dig up flower beds.  Willing to pay $10/hour plus a little for gas.  Cash.  Must be done on weekend so I can supervise."  They send the email and wait for the response, which might come from any number of folks.  Each responder might want to share references, experience, or negotiate a different price even. 

I've got a buddy who is very skilled at repairing and replacing well pumps.  Had I known, I would have called him and paid him instead of the local well people that did a great job, but for $700, they should have.  Wonder what my buddy would have charged.
