I was in your position about a year ago, with 500 tt and about 10 hours multi. I was lucky and found myself a job flying skydivers. Then I was unlucky and quit because the conditions where, well, dangerous. Then I was lucky and found myself a job doing king air delivery, then I was unlucky because again, not only was the situation dangerous, it was only about 10 hours a month, not a very good way to build time in a hurry.
My recommendation, sigh, sorry, get your CFI and go teach. It seems like that is really the only way to build time up in a hurry. Don't be like I did and avoid it, because in the long run, all it will do is slow you down.
I will also say, don't believe all the crap about instructing being the best time you will have and a great learning experience. It's great for about 100 hours or until the first time a student tries to kill you.
Ok, I'll give you that some of the cross countries are fun, sorta, but how many touch and goes can you do before you go nuts.
Anyway, all I have to say is that if you get your CFI, manage your time and your students to build the cross country and night time. Don't wind up short with 1200 hours and not enough x-c and/or night time, which seem to be the hardest to build when you are instructing. Most important.. be the best instructor you can be, provide the best instruction that you can give, and never.. ever.. ever let the student get the feeling that you are there to just build time. If you can't do that, all you are going to do is create bad pilots and give the whole industry a bad name.
At about 1000 hours, apply to all of the cargo places, Ameriflight, Airnet, ect, and call them up and let them know that you are close to your 135 mins. That's really the important part, and honestly, I don't know if it's working, because I haven't heard anything back from them yet, and I'm right at 1000 hours.
The biggest problem I've had is the frustration. Don't let it get you down, make some spare time, find something other than aviation to do in it. This will keep your brain from turning to jello and keep you from getting depressed when things are moving slow.
If you keep at it, things will turn around, and hopefully, there will be jobs had for all... if not.. make sure you have a backup plan.
Good luck, and PM me if you have questions, or need encouragement, because most of the people are not very encouraging here

don't let that sway you either.
