A No Spending Idea

I have heard of people going for certain amounts of time without spending money except, of course, for regular bills, food, and grooming necessities. I think I would like to try this. There are a few reasons why I would like to try this adventure: 
1) I want to stay home with my baby (aka remain unemployed) 
2) I have a lot of time to spare by helping others 
3) I am getting used to being broke 
So, the plan would be for one year...to barter my time for goods and services. Say for instance someone needs a babysitter. I would babysit in return for...laundry soap, postage stamps, baby clothes, clothes for me, etc. Or I could clean up a beauty shop in return for a haircut. This way I am helping out someone and getting the things I need (or want) in return. 
I will be starting a new button making business in January and will be spending money on that for supplies, booths, etc. A majority of the profit (minus purchasing  supplies) will be saved. There is no point in me starting a home-based business if I am just going to blow all the profits on stuff I don't need. 
I will also spend a budgeted amount of money on sending swaps on Swap-Bot. I have a lot of craft supplies that I no longer use that I can swap on there for things I can use. 
I would like to keep a running list of things I need on here. This is all just an idea for now. I need to let it swim around in my head for a few days to make sure it is something I can commit to. Any thoughts on this?
