In the Colorado market, knowing how to structure and sell an offer for maximum impact is really the difference between success and failure.This is something you will never have with a green agent who has the time and willingness to write 100's of 1% offers...hence, both your time and theirs is completely wasted.I know this doesn't answer your question about how to convince an agent to do all that work for you with little chance of return on their time, but hopefully it gives a little more context to all the answers above that say in one way or another, it's probably not the best route for you to take anyway.

There is an unbelievable wealth of info on Bigger Pockets if you haven't had a chance to explore it.  

I was in a rural area and had little chance of getting help there.

Or by chance sooner because there are multiple properties?

It may be a chance to get owner financing, but that alone is not a reason to get properties that are worth less than the mortgage. 

Maybe select the family with the highest income to reduce non-payment chances.

The VA doesn't have a particular time frame printed in any of their directives, but if you try to use your entitlement again, before 1 year, chances are they will look at you extra hard; you would need to have a pretty good reason (new family member, significant change in health, relocation to completely new area).  

I just takes a while and there are LOTS of folks now getting in the market so if you can get to the home owners before it comes to the courthouse, you have a much better chance of making money!  

In the space you are in, high debt, short time on job, and short credit history, your chances of your "speaking with lenders to get better rates" stand little to no chance of moving the needle.
