I have found that any invention marketing service that advertisies on TV, radio or in printed media is a front money fraud. If you need help in marketing, get recommendations for honest brokers through a local inventor organization or a major manufacturer of toys and games, many of which provide agent lists. Nineteen states have legislation to protect inventors from conmen. Tailor yourtoy or game to its requirements. One of the amateur inventor's greatest downfalls is inventing in a vacuum, instead of for the marketplace.
Ideas are like belly buttons, every person has one.
For example, if you are patenting an electronic circuit, you want a patent attorney who has a degree in electronic engineering. Horses for courses. Hire your own professional patent searcher. It's cheaper than going via the law firm. Hire your own professional draftsman.
