Well I tried Kalitta and apparently they want someone with more heavy and international flying experience, flying the regional jets obviously gets me neither of those.
I think you posted somewhere else and didn't hear what you wanted to hear.
Kalitta doesn't necessarily need international experience, nor heavy experience...just more experience. 800 hours of multi engine experience, but you want to jump into a B747.
I think what we're seeing is the me-now generation, as in I want it, give it to me now. I'm not going to glaze your eyes with a recitation of the good old days and give you the pay-your-dues lecture, but you surely need to realize that to apply for any job you need to meet some basic qualifications. Your total time doesn't meet the posted minimums, to say nothing of your multi engine experience.
Other posters have give you good advice. You need to get some experience where you are. Get some solid PIC experience, increase your total time by about 2,000 more hours, and push on. The industry will still be there for you then, too.
Bear in mind that a lot of folks have already put in 15 or 20 years before they get to that 747.
