trying to creat an uber like app

A plus is a former programmer or someone with a computer science background/education. The more specific their knowledge/experience is to what you are doing, the better. One approach is to search the U.S. Patent Office roster of practitioners (attorneys and agents). To do this navigate on uspto.gov to Finding a Practitioner. You can search in your location, because you probably want to see the practitioner in person to better explain your invention. As a rule of thumb, the lower the practitioner's registration number, the more years of patent experience. Go on the practitoner's/firm's website to learn more about her/their credentials/capabilities. There is also the following to consider, which may or may not apply to your situation. Practitioners hear all the time about ideas for which the implementation details are thin or missing. Certainly the practitioner's skill comes into play and is likely one of your key considerations, but keep in mind that at the end of the day either you have a fully formed idea or not. Think of it like this. If you are explaining your idea to an ordinary telecommunications systems designer (or fill in the blank) and they still do not know how to build an implementation of your idea without putting in ingenuity of their own, then it was not a fully formed idea to begin with and was not enough to proceed with writing a patent application. Your invention mus be explained in the patent application in such clear terms that one of ordinary skill in the art would know how to make and use your invention without undue experimentation. Finding the best practitioner to write and prosecute your patent application (which is what was just discussed) is one, and an important, milestone. Other important goals are finding funding, if you need to; assessing the market for your invention; and obtaining other intellectual property such as trademarks. The same patent practitioner, or other sources, e.g., business lawyers, potential licensees, can assist you in this regard.
