It has just about always been a bad idea to be your own patent and trademark lawyer. As of July 10, 2008 it became an even worse idea. The USPTO issued new rules about appealing a decision by a trademark examiner. The net result will likely be that, if the trademark application is not done right the first time, you are toast on appeal. The days of "I will file a trademark application myself, then hire a lawyer if things get difficult" are REALLY over now.
Hiring help is usually about priorities, not money. You have the money or can get the money if the asset is important enough. Trademarks build loyalty and good will.
