These are some interesting plays on the letters DAS!
I have a strong preference for the words "Discovery Audit Services" (note services vs service) 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.
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.
Thanks for your comments, thats really helpful, i can work on that, but remember that only top 5 designers in your contest can actually upload new logos.
