Or you can try another approach: demonstrate value to the company by finding solutions to problems they didn't realize they had in the first place.
If you are a designer - offer a mock up with descriptions of how your design is an improvement.
If you are a programmer - provide bug fixes or build a feature that the company's product lacks.
Provide value and make yourself indispensable so that they will want to hire you before you even ask.
Don't just approach the company asking "what can I do for you?" instead approach them with "I respect your company, here are some solutions that I think will benefit you. Let me know if there are any other ways that I can help."
