Many people have good ideas, and often different people have the same good ideas around the same time. The one that makes it to market is usually the one who can afford to protect and then develop the product for sale. This is a long, tedious and expensive process. That is why many patent lawyers do not participate in ownership of an invention in exchange for legal work - because even if an invention is patented, it many not make it to market for any number of reasons including inability to make the product for a saleable price; consumer acceptance; and marketing. Be careful of any company that claims to help you license your invention - a number of them make money from you by way of fees and not from licensing your invention. These companies, called invention promoters, are required by Federal law to inform you BEFORE you enter a written contract of statistics of their clients who have made money from licensing efforts. What you need is an investor, such as an angel investor, or perhaps a loan to finance your efforts.
