You can file for a patent without a patent attorney or agent, but I wouldn't recommend it. Patent law, like other law practices is highly specialized and there are many important things to consider as you apply for a patent. If your invention is not successful (that is you don't make much money from it) then it really doesn't matter, but if you are successful, then having a patent application that you filed without professional help could leave you very vulnerable if your patent is challenged. Of course I am a patent attorney and have vested interest in having people use a patent attorney; however, I truly believe that it is in your best interest to hire a patent professional if you want patent protection. Although I am an attorney, I wouldn't dream of not using a real estate attorney to close on a house or a tax attorney if I had a tax issue, etc. The law is constantly changing and you need to have someone familiar with the practice in order ensure you rights are protected. I understand that money is an issue, but I think it is often just a waste of money to try to file a patent application on your own. The patent process takes some time with most applications taking between 18 months to two years before we hear back from the patent office. The patent office has been working to improve the time and it does seem to be improving, but it is generally not a fast process. Some applications or more complicated than others and having a good patent professional to help explain the process is very important.
