Hmmm. I would say: "Ideas are cheap. Execution and business skill are priceless." It has taken quite a few of my own ideas to learn this.
Getting your provisional patent filed will allow you to mark your product as patent pending for one year. But if you are not actually making a product, this becomes a shot in the dark.
A decent patent attorney will do a provisional for around $1k flat fee with you doing the lion's share of the work.
If that is too much, I would have you think about how committed you are to this idea. It sounds like a good one if you had the product designed, built, packaged and sitting in front of you waiting to go. Are you willing to go through the process of getting it to that point? I would pursue creating a product before pursuing protecting an idea.
