Keep in mind that collection agencies are NOT any direct competition to you. Collection agencies tend to focus on pre-judgment debt. They do this by sending dunning letters and making annoying phone calls to the debtor. The only judgments that collection agencies usually collect have been awarded to their existing clients. Your competition, should you find any, will be other judgment recovery companies.
Most attorneys specialize in one area of law or another.
Only a small percentage of those attorneys specialize in collections. Even then, those specializing in collections will only go after 'Big Ticket' judgments and usually require a large retainer fee up front. The whole idea behind small claims court was to have a place where people could settle their grievances in court without requiring representation by an attorney. The laws in place to enforce judgments basically encompass the same generic procedures throughout the United States as well as Canada. However, you will need to research your state's specific procedures as they may vary slightly.
