CodeFellows/Udacity/College is expensive. Hack: Figure out what they teach you, and find other, cheaper sources of the same information. (edit: Check out Zed Shaw's stuff http://learnrubythehardway.org/book/ http://learnpythonthehardway.org/book/)
CodeFellows/Udacity/College says they teach you what you need to know to get a job. Hack: Ask employers directly what they look for when hiring. Learn that instead.
I don't have experience/proof of skills. Hack: Start posting your work online. (Get a free blog or use GitHub or something.) Even if it's a tiny thing. Bit by bit, day by day, you'll be proving that you can ship something. When someone asks what you can do, show them the site. (edit: A shining example is Jennifer Dewalt's 180 Websites in 180 days: http://jenniferdewalt.com/)
I don't know people who can help me. Hack: Find your local web development meetup and go. Don't sit in the corner. Meet people. Get their contact into. Tell them what you're trying to accomplish. Ask them for advice. (People love to give advice.) Email them later and let them know you enjoyed meeting them. Thank them for their advice. Build relationships.
