Logo + Website Header for robbagby.com

robbagby.com

I run a blog about software development. My blog contains posts that teach people how to take advantage of Microsoft software (I work for Microsoft). I am moving my blog to a new platform and want to brand myself. I am passionate about software and teaching. The goal of my writings is to take the complexity out of software. I think of what I do as demystifying or simplifying software development.

The target audience is software developers and development managers. Although I work for Microsoft and am not a training company, that is probably the closest market to compare my blog to. I tend to train folks. I like to keep a pretty professional feel

I have chosen the theme for my blog and am looking for a logo that will fit within this theme. You can find an example of the theme here: http://www.studiopress.com/demo/corporate.html. What I am looking for is the logo and the images for the top header. I am not married to any of the specifics in the banner in the example. For example, I foresee eliminating the globe on the right hand side.

What I am looking for is a simple design. I tend to like simple fonts and am drawn to logos like the following examples:

http://tinyurl.com/TrainerSample-png
http://tinyurl.com/GameSample-png

I'm pretty open to what the graphical part of the logo looks like... Use your creativity. Some high-level ideas would be around teaching, learning or just my initials... Those are just ideas, I'm not very creative.

Here are the 2 images from the web theme. One is the old sample logo from the theme and the other is the background image of the header:

Just to be clear, I would like logo itself (photoshop format) and 2 images that I can use in the theme like the 2 above (png).

Thanks and I look forward to it.
