A provisional application is a first step in obtaining a patent for an innovative idea in the United States, and serves primarily as a priority document used to establish the date of innovation and preclude others who later file a provisional covering the same idea. No patent is granted based solely on the information obtained in a provisional application. It should be understood that a patent, if granted, is based solely on the information that is provided in the non-provisional application. In terms of content, the provisional application provides what can be viewed as analogous to the frame of a picture with a fairly general description of what the painting "will" contain. It is important to ensure that the provisional application covers, in general, every aspect of your idea since you aren't able to add new aspects in the non-provisional application claiming priority from that provisional application. For example, if you discuss generally an idea having A, B, and C in the provisional application, you cannot disclose aspects D, E, or F in the non-provisional application. Certainly, patent law can be very complex and the information discussed above may be difficult to wrap your mind around. This is why it is always recommended to seek counsel experienced in patent law when looking to get a patent on an idea. Even so, the quote you've received does not seem unreasonable for completing and filing a document that is relatively straightforward and limited in format. The higher fees you expect are sure to come with filing the much more detailed and lengthy non-provisional, the application from which a patent is actually granted. Hope this helps!
