Free or barter for work for a decent mountain bike.

I am living in a sober living house and have been clean for three months. I am newly baptized and have seen how quickly god moves for his people. Within a few months of being baptized I broke a 30 year addiction to meth and have no desire to go back. I would be greatly blessed to get a bike and I'll work for it as well. Thank you and God bless your household
