I have a strong preference for the words "Discovery Audit Services" vs the letters "DAS". The symbol needs to reflect more the recovery of money, stocks, cash than property as in real estate. So it's kind of like we are treasure hunter auditors looking for money that belongs to others. More emphasis on the words vs the DAS.
We go into companies and audit to find money or stocks, or whatever that the company may be holding that belongs to someone else. If you would focus on the words and present symbols that are simple and flow, capturing what we do it would yield a better result.
The magnifying glass concept is cool. It's a little too big. Maybe delete the DAS, enlarge the letters of the words and then play with the optimal proportion?
