You could create a cheap website and drive traffic to it with SEO or PPC.  

You can only allocate a couple % for this - the other regularly recurring expenses like roto rooting, regular tree trimming, asphalt sealing, etc can all be allocated as part of your diligence and be pretty firm year over year.

Currently I spend an hour a day driving for dollars (seeking out distressed properties).

Prior to Bigger Pockets and hitting the real estate bug, driving next to these "temptations" I would get overwhelmed with the feeling of jealousy, borderline envy.  

After taking a small glimpse into what keeps me from sleeping no more than 4 hrs any day of the week should in itself paint enough of a picture as to my determination and drive toward success. 

Remember, if you add money to it, with out changing what you get out of it, then you are driving down your rate of return.  

Again, its my opinion that those signs are unneeded, do they work (Yes), but would I personally stick to societal norms to reach out to individuals who half the time do not even look up from their cellphones while driving, no. 

If that doesn't work for you then you can always drive for dollars on weekends and look for houses that are abandoned looking or in disrepair then look up the owners address on the tax assessor site and write him/ her a letter stating that you would like to purchase their house if they are interested in selling.

For all the locals, drive west on 10 mile and you'll see what I mean.

Drive an hour south and I bet you will find something more reasonable and it might cash flow.
