What is the easiest way to collect a civil court judgment in my favor for fraud in a 2008 case.

I won the case against a TX corporation in 2008-2009 for fraud, but their lawyer laughed at me on the way out stating, "you should have settled because now you have to collect and won't see any of your judgment monies..." I filed interrogatories in 2010 and another plaintiff in the same case against them collected from their bank account, but then they shut the account down before I could... Then I went to file interogatories again to find out where their new owners home or bank account was, but the court said I was using the wrong form civil/county and that I didn't need to file with the court, but just had to send the corporation the interrogatories. Should I just hire a collection agency? Or a lawyer that won't take payment until the collection is recieved? The judgment is around $5,000 now I believe as it has collected interest every year.
