Don't take this the wrong way. BUT, If you're here with your first post, offering to fly for free to gain hours, asking a professional audience, then you may not like the answers you seek. Why would a professional pilot want to assist someone to fly for free, or more importantly, why would YOU want to fly for free after what was probably an expensive exercise gaining the IR etc?
Just my take on it. Don't dumb down the salaries! Don't reduce the pay for pro pilots who do this for a living, not just for fun.
Unfortunately, you have probably picked the worst time ever to find an IR job with low hours and zero experience. But, things do change, and sometimes very quickly. Being ready to go, current, and able to say yes to any jobs that come your way is a big deal when the jobs come along.
Good luck, many of us (me included) have been in your position. And yes, there really are a lot of old pilots soon to retire, so stay positive.
