I have my CFI and I STILL can't find a full time job - CFIing or towing banners.
Edit: I realize my post had no useful information.
So I would make a plug to spend the time getting your CFI. I got my commercial couple years ago and I thought I was all that. Commercial multi? I'm good to go! That Shiny jet is just waiting for me. Then I found this place (and reality). But most importantly, I started studying for my CFI and realized how much I DIDN'T know. You will get such a better understanding of aviation by studying for your CFI, even if you dont use it - although you owe it to yourself to teach at least 1 student.
I would argue that a 300 hour commercial pilot with no CFI would be at a disadvantage compared to a 300 hour CFI...
