I am a patent lawyer. Contact me and I will give you more on your options. While some full utility applications cost $10,000, you can file a provisional patent application for far less. I usually recommend reading some related patents and trying to draft your application yourself and then retaining an attorney to give suggestions on changes and additions that may be needed.

When you got legal questions the internet if fun, but if you think your idea's valuable ya gotta talk with a lawyer. Sooner is better than too late.
