I like simplicity and clean lines; the sort of logo that can sit by itself on a blank background and look elegant and striking. The logo needs to incorporate the word Billet, but I'd be open to incorporating a mark as well if the mark was of the type that could be displayed by itself and still make sense (the sort of thing that could become an icon for the business). The words "Accounting" and "Consulting" may be incorporated into the logo, but it's not required. Most of my business will be transacted remotely through the web, hence my openness to Web 2.0-style designs. The logo also needs to printable on a white background for letterhead purposes.
The selling points that I want to convey are my youth, energy and the fact that I'm not a boring, introverted bean counter. That said, the logo needs to remain professional given the industry I'm in.
These are a few of the words that come to mind when I think of the business (I don't want these in the logo...they're just for your creative thought process): Professional, trustworthy, flexible, simple, quality, energy, modern.
I'd like to avoid graphical references to money and finance in the logo (dollar bills, dollar signs, coins, stock charts, graphs, etc.).
