Design two logos for my blog

I need two logos designing for the same brand;

One for my Wordpress blog - www.inspectorgraduate.co.uk
One for the Twitter and Facebook profiles

I need a logo designing for the header of my blog, ideally 1015 pixels wide and 276 pixels in height.

I also need a logo designing for the Facebook and Twitter profiles for my blog.

The logos are both for my blow, Inspector Graduate, but they need to be different due to the dimensions etc. I have attached two sketches of what I had in mind for the logos, however they are just sketches so your input would be much appreciated.

Who ever is successful in designing the logos, I would like to talk with you before you begin the job.
