(Putting on my hiring manager hat) You may not even get past our HR for an interview without the college. But ignoring that for now ...
What's your experience? What kind of coding projects did you do that you can show an employer that you have the chops? Volunteer work, self-study assignments, written articles, anything? Even if it's not hard-core programming, if you can show me something you've done where the skillsets can be transferred to my job requirements, I may take a chance on you.
Even better if you have that on a laptop you can take to an interview, or it exists on the web, and show me in person during the interview.
I've interviewed a few people that tried the approach of 'I have a college degree, therefore I don't have to show you anything.' None of them were hired.
Certifications also help as it proves a certain amount of skillsets.
Also I wrote the article Contracting: How to go out on your own that may give you a boatload of other ideas for your situation.
Also I've noticed a pattern during my 20ish years in IT in that when the economy is good college requirements are relaxed, and when the economy is bad employers will often use a college degree requirement as an easy way to weed out the large number of candidates.
