Need a new logo

Information for the business: Recruitment Company
Industry: Business
Type of logo: Word mark, Abstract mark, Pictorial mark
Brand name/slogan in logo: Will provide on contact
Ideas for the visual style: Simple, professional, memorable
Things to avoid: Too complex, too many colours, unprofessional
Preferred colors: Not too many colours, simple
Where the design will be used: Website, business cards
Extra notes: I need a logo for my company website. It has be professional and also memorable.

I think the simplest logos are the best (Google, Facebook, etc. simply have their name in a specific font), however I wouldn't mind an image associated with it also.

I am a perfectionist, so will keep going until it is perfect. I will also require the vector image.

This project is just the beginning. So if I am happy with the design, I do need more work done, including more logos, business cards and other stationary.
