The following isn't legal advice and I'm not your attorney. Keep looking for someone with related but not direct experience. Many of the details of patent prosecution are procedural and legal, not exactly technical. Anyone who has done patent prosecution is better than a technical expert. Even if you get a patent passed the examiner, you might have gotten claims that were too broad or too narrow. You might have made statements during prosecution that make asserting the application difficult. You might have written the claims in a way that is difficult to enforce.
