Yes, there are many people willing to take your idea and your money, destroy your rights and not give you anything in return.
Or, you could see a licensed and registered patent attorney for legal advice, if you believe your invention might be valuable. As the inventor, your name would have to be on any patent application, regardless of whether you file it yourself or someone else owns the rights to it and files it for you (whether investor or employer).
Add: Oh, sorry: upon re-reading the question, you already have a patent, which would give you the legal right to sue others who make, use, sell or import it in the country where your patent is issued. Yes, there are "marketing" companies that can help you find a potential market for your invention, for a fee or for a percentage.
Nobody is going to give you money just for your idea. Start with the three F's: family, friends, and fools.
When you are selling a product, then you can get investors.
No, you create the patent, otherwise its not yours.
Is there a company you can submit a patent and if their intersting they should invest in it?
