Did you realize that this is the third time within 1 hour or so that you post one and the same thing?
All right maybe you want to have it somehow more organized and more "on topic". So here are my 2 cents:
First of all I don't think that you have to give your real name in this forum and especially not your mail-adress unless you have the best ***ing spam-filter available
All right: You are right it's too late to apply for this fall... deadlines are typically around december 15th to january 15th and most of the universities even stopped accepting "late" applications. So you'll have to apply for the next cycle... sorry. Further: 90% of the students applying for PhD's in the states don't have enough money to cover their living expenses let alone tution.. so we are all in the same boat. When you apply you will be automatically considered for funding (unless you state explicitely: PLEASE DON'T GIVE ME MONEY!!! ) whose provision is said to be based on merit not on need.
Comments on your profile:
1)your university seems to be pretty tough in terms of grading given that you are 2nd best with a GPA of 3.54. But this is not sooooo important for int. students although it's also not very helpful either I'm afraid...
2) It would be interesting to see which math courses you took/had precisely. Because Tourism management itself doesn't sound like THE best program to prepare for an econ PhD and I suppose there are 1-2 profs sharing my opinion. You could use the time until the next application cycle starts to take additional math courses: E.g: Have a look at the curriculum for studying math in your country and take the courses recommended for the first semester, or if you feel better prepared take the courses recommended for the 2nd, 3rd or 4th semester...
3) YOur GRE is fine and your RA/work experience is also great and is probably the basis for you to get good letter of recommendation's
4) Have a look where other students from your university did their PhD studies in the states and contact them. If they perform well the adcoms are more likely to say: "Ah again one of the brilliant guys from University "X" ... we should take him"
5) If pedigree is somehow available: mobilize it
6) Aim high, don't underestimate but also don't overestimate yourself: i.e.: talk to your profs and ask them what they think
All the best
