The most common ways people end up in industry without a degree are:
- They've already been in the industry for years, and didn't need a degree when they started.
- They worked their way up/across from some entry-level position that didn't require a degree.
- They know someone in the position to help them get past HR screening.
If you're currently a senior in high-school, you want to get a job in the industry, and you know that will be extremely difficult without a degree then why aren't you planning on getting a degree.
If you're concerned about cost, there are numerous scholarships, grants, student-loans, and government funding available in most places to help you obtain your degree without having to deal with the entire (or in some cases any of the) cost up front.
If it's about your grades not being up to the entry requirements, you should work on improving them, and might also consider options such as summer or night school or repeating classes.
If you want a job in the industry the best approach would be to do everything in your power to get a degree.
As for your portfolio, this might just be my ignorance of how that particular site works, but I don't see any actual examples of your work on the linked page... Your portfolio needs to display your best work and your contact details immediately, or it won't help you to get a job. Someone busy trying to decide between applicants isn't going to take the time to find your work, it needs to be right there for them to see and it needs to grab their attention.
//EDIT: I figured out the portfolio -- I needed to click the little "projects" link. You should link directly to that page (http://www.behance.net/WardPortfolio) rather than the WIP page so that your work is immediately displayed with no extra effort required on the part of the viewer. You might also consider getting your own domain name, even if you're just going to point it to that page for now -- that way if "behance" go out of business you can just point the domain to a new portfolio page and any links you've posted or given out will still be valid.
Hope that's helpful, and best of luck!
