Know-How Exchange : Taglines/Names

I am starting up a contract security guard business. I have 14 years in the industry in management. I want to cater to higher end clients (Class A/B offices, High end retail, Banks, etc.) not your typical take any contract just to get paid company. I want my clients to feel safe with us on the job and I want them to feel as if they are exclusive enough to do business with us (a little reverse psychology, I guess). My company name is Alliance Facility Management, Inc. (we also provide janitorial and maintenance services to facilities). The security division will operate as either Alliance Security Management Group, Inc or Alliance Security Associates, Inc. Any ideas will be welcomed graciously. Thank you!
