Stock up on canned goods and maybe rice cakes. Move in with a relative who will let you cut the lawn for rent payment. Shop at the local good will and get on good terms with the folks at the local soup kitchen.
Yeah you're right growler, the local Good-Will is probably out of the price range, hand-me downs might be a better option at least for a few years anyway. My other thoughts are, Does your wife work and make enough to support the family if you have one? Do you have alot of savings put away to pay the bills? Are there generous relatives nearby to help out financially? Seriously, unless you're already connected so to speak and have your networks set, it aint easy to get established and be profitable, not easy at all. Now if you already have set customers such as builders or multiple property landslords and they will keep you busy, well that's a different story. Like already mentioned here, be more specific on what the reason was for your initial failure.
Probably the most important thing is to have a couple of "good" customers. A "good" customer is one who can be depended upon for regular work, pays promptly, and, when times are lean, can even be coaxed into creating some work for you. Such customers make a business, by covering the rent.
