Well, don't know what you have vehiclewise... but if you got room for a push mower and weedwhacker, why not start looking for lawns to mow?
You will "have" to make yourself finish the job though since they won't pay till it is done, but you will be making some really good cash.
Chances are you WILL end up having to report that cash cuz guys like me (accountants) will tell their clients to send you a 1099. But owning/running your own business CAN get addictive!
I had a friend who worked his way thru college running his own landscaping deal. We both graduated with accounting degrees...I think he tried it for a while and actually decided he liked working for himself more!
So now, 13 years later, I see him at lunch sometimes and we share a booth and he runs a landscaping company and I run a CPA firm. He just hated working indoors, has a good tan, in great shape...works 8-9 months a year and makes pretty close to the same thing I do! (Heck he would prob make more but doesn't want to mess with employees who don't show up, etc heh

)
So...it is all about how YOU enjoy life...personally I LOVE sitting here in my office, a/c blasting, surfing the net (uh...working), and crunching numbers.
Final .02...yep, did the hard labor stuff too, hung drywall for 3 months until the manager found out I knew how to type and do bookkeeping...and have done oddjob stuff during college digging holes for fences, lawncare, etc.
1/2 of college was paid for by working 40 hours a week 3rd shift as night auditor/manager at hotel and I can tell you getting off work at 7am and having a 8am class sux...
Sam...glad its over/pays someone to mow his lawn now (ie lazy
b@st@rd)...Hinton
