Okay, I need help (also known as "my adventures in home repair")

I've been trying to do as much as I possibly can on my own.  But I've come to a point that I just can't do it. 

Back in March of 2007, I had a friend come over and fix some water pipes running under my bathroom.  In August of 2007, I had my water shut off.  Apparently between then and now, the pipes that I had repaired have become damaged again. Not only that, my ex-husband had come over and removed the water softener we had.  He left the pipes undone when he took it.  I managed to get those pipes repaired on my own, (and replaced a gateway valve that was leaking) last Friday.

This morning, the water was turned back on, and from what I can hear, the water is not making it to my my bathroom, and the water pressure is so poor, I can't get the cold water to any other faucet in the house. It sounds like it is coming from under the bathroom and utility room.  This area is a crawl space and I need someone who has the experience/ability to work in a space like that to come help me.  I really don't like asking for help, and I can't pay anyone up front to do the work, but I can buy the parts and  I will have a few dollars to spare in a couple of weeks to pay for the work.  Is there anyone out there that can assist me?
