My intention is for the name "enthcast" to be all lowercase lettering (including the "e"), with the "n" in superscript. Think about exponents in arithmetic (say, 10 to the 4th power would be represented by the numeral 10 and a superscript 4).
Below the word "enthcast" should be "Marketing & Consulting" - written exactly like that, not with "and" spelled out.
The superscript "n" idea described above ties into the tagline for my company - "Unlock Your Exponential Growth." I am unsure of whether or not I want the tagline to actually be a part of the logo, so it would be helpful to see options that include it and options that don't.
The final part of the logo is the icon. Again tying into the tagline, "Unlock Your Exponential Growth," I am thinking about something involving either a lock or a key. I have a Web designer working on my Web site, and I'm thinking of carrying over a lock-type icon to use as the navigational buttons on the site (think 4 combination lock icons down the side, with "Home," "About," "Services," "Blog," etc. That doesn't mean that the logo icon HAS to be the lock - as I said, it could be some kind of key as well.
No clip art. Need several file formats with complete logo, as well as just the icon in a separate file. Colors: Reds/Blues w/black contrast. Yellows/Oranges might work as well. Will probably give additional work to winner (biz cards, etc.).
