While it is possible to deal with the USPTO on your own, if you are asking this question you don't know enough about the process to do it successfully. Therefore, you should hire a patent attorney or a patent agent to prepare, file and prosecute your patent application in the USPTO. No matter what, you will be dealing with the USPTO.
Plan on spending 15-20K...just for a U.S. Patent...and there is no guarantee that you will get the patent.
