Looking for logo

Im needing a logo so I can start branding my new website. Omen Competitions. I need logos clearly to be transparent, suitable for dark back grounds & light backgrounds. Need also vertical and square versions of each design. I really need full logo and hex codes for any color used. The logo will then be used so I can plan website design.

Dont have a particular idea right now. But one was a ravens head with the name Omen Competitions however id like to see a few designs so I can pick or tweak before picking a final design.

I really need work started now so please dont give a proposal if you can start right now, thats not tomorrow morning or next week. I really need it started now as I was to submit this to web designers today. So speed but perfection is needed.
