Unless you have tons of time in make and model or are a citizen of the foreign carrier you wish to work for, they will not hire you. There are enough pilots on the streets that are desperate enough and have the time, but still cannot get hired.
There is no shortcut to a 121 job. There is no shortcut to any pilot job that pays enough to really live. You are lucky to get a job that pays for food or rent, not both. Right now, I have what is considered a great job in this market. My flight pay is pretty high and I get to fly some interesting aircraft, but if you consider all the work I do outside of the cockpit that I do not get paid for, the job does not look so good. I sit around the airport all day everyday waiting for anyone who walks in and wants to fly. I am at the airport organizing files and preparing for flights 84 hours a week, but on average I only get paid and fly for 10 hours a week. My income is dependent on weather, aircraft availability, and more importantly, a steady supply of customers. There is no type of flying that is worth the stress of not knowing if you will be able to pay your bills no matter how hard you work.
The best option is to enjoy training now and not plan on a career in aviation. Look into other careers. Nearly any other field will allow you to earn more money than a low time pilot job and you can still fly on the side as a part time instructor.
On a side note, a doctor told me as he got in the plane that he was jealous of my job. He said he would gladly trade places with me because he was sick of working 60 hours a week in a hospital. That made me feel pretty good until he told me he was buying his own aircraft and wanted to know if a Cessna 421 would be big enough for him and his wife!
