Company Logo Design: b-fusion

I have just set-up a new company and require a logo. The company name is b-fusion, the name is not specific to an industry but simply represents the coming together of people and ideas. Ideas for the logo I have had include nuclear fusion, text b-fusion with some element of it fragmented and coming together. Please don't feel you have to go with any of my ideas yours are probably far better. I will need to see a portfolio or website of previous work. If you have a couple of quick idea sketches about a design for my logo it will help me descide. The Job (After selection) I will require 6 rough ideas for logos, I then decide which I like most and then request you to create 3 or 4 variations on that design.
