Platinum Investment Partners/Platinum Asset Solutions/Platinum Lending Solutions

Desired Color Scheme:
Platinum and Steel Blue with maybe Black

Desired Style:
Wall Street Professional Style

Accepted File Formats:
Vector Formats (.eps, .pdf or .ai); Layered Formats (.psd or .tiff); Both Please

Platinum Investment Partners is the parent company, with Platinum Lending Solutions and Platinum Asset Solutions being the two subsidiaries. We are looking for a logo that can tie in the "Platinum" theme for all three.
 
We desire a "Wall St." type look... clean lines, simple, professional.  We like the idea of having a roman pillar as the spine for the "P" in Platinum, as a symbol for strength and longevity, and possibly the rest of the name in a formal script, to soften the look.  We welcome any other design suggestions you may have.
 
The main company we need a logo for ASAP is Platinum Lending Solutions, as this is the company we will launch first, but we'd like to see what ideas you can come up with to tie in the parent company and other subsidiaries.
