above is plenty good advice. (going thru expenses, limit them etc)
here is another: you do have extra time and vehicle skills. why not go thru ebay/craigslist/hemmings/classifieds for something simple fixer upper vehicle.
car, bike, moped, boat (engine), even lawmowers are options.
something like a common and still "desired" car (toyota,honda or pickup, what ever is popular there where you are) with engine or tranny problem and fix that up and re-sell.
you just need to invest the time and effort.
sometimes you can find deals that offer the broken car with spareparts in the trunk waiting.. (owner likely just realised after buying the parts that having it professionally fixed by mechanic would be more than what car itself is worth. and they either dont have the energy or skills to do it themselves.)
this could give you something constructive to do with extra time you have, and if you do your math and research ok you should make some profit aswell.
**then, go thru all family and friends, let them know you have couple days off every week, just in case if they are in need of handyman around the house or garage, you are available for food and drink, and possible for some small cash outlay. (hey, i too would pay someone 20dollars to mow my lawn for me. most people have some projects they might not start on their own or just need an extra pair of hands to help out)
**like emptying friends garage (yeah the one his wife has been nagging him to empty for years now) could yield lot of useful stuff that is now going into the trash. pick them up and sell them in your garagesale/ebay/fleamarket.
i did the garage thing myself: year ago i took one trailer of old furniture stuff to local 2nd hand store owner and asked him a bulk price for lot. walked off with 200$. -i could of sold them slowly myself for 3-500 or so, but was easier this way.
i have pulled during past 3 years six similar lawnmowers out of trash etc. 1 worked as is and is still in use. 1 came to life with cleanup and was sold. 2 were built into one and that one got sold. 5th one was given away to a friend whom needed spare parts. the 6th and rest of the dismantled/harvested one is still waiting for number 7 to appear so i can get it running and have it sold.
i have also bought stuff from china and usa and sold them here for small profit. couple knives and lights lately. if i had more money and time to wait for the purchased items to be re-sold i would do more of it.
i got 20 nfl/nhl jerseys myself, and pretty much all of them are "free" to me as i ordered extra ones and sold them here to finance my own jersey, ordered 3-5 and kept one. (decided to stop importing them for fun when i started to have my money tied up in a jersey for 3 months before it got sold. now i just ask friends if they want one and then order one and take that 5er on top of pricetag.)
