Well, I cannot directly answer your question, but I can lead you where you want to go. First, are there any schools in your area that teach IT? Can you get financial aid from them? If you can, go to
http://www.fafsa.gov student loans, the most of which you do not have to pay back until you graduate. They can be found here.
http://www.salliemae.com/. And these sources mostly are available without a credit check.
Now that you can find money, try looking at :
Occupational Outlook Handbook, 2008-09 Edition. That is the federal government occupational outlook handbook. You can look at both careers, or even more, and see what they are expected to do in the future. Look again, at your local colleges/trade schools websites to get the other info (exams, cost, E.T.C.). Finally, go to :
Job Salaries-Performance Reviews-Compensation software- Salary.com and look up what the expected salary for that job is in your area, and it even compares it to nationwide salaries. Just never set it to Miami, you'd just get depressed. That is the best way, I think to figure it out. Now if you could help me with my C++ homework...
