Design a business logo

I have a business and I am not happy with my logo. I would like to employ someone to create a logo that is big enough for me to use on my website, business card, letters, signature etc. I would like it in high resolution. If you can have a look at my website - www.phraseframe.org and give me a rundown in your proposal on what you think would look good as a logo for this site, from what you say, I will work out which idea I like best.
