I need a professional graphic for my hourlie

Design details: I am having increased success with my hourlie for CV writing (see my profile) but I don't think my image is professional enough - I want to do something to make it really stand out but I really want it to appear to be crisp and modern, which my CVs are. Thus the dimensions of the image will be suitable to an hourlie on here - this is the only use for the graphic.

I want it to primarily be professional... 'official' almost because I do this professionally both on here and in my paying job, I'm not just taking a punt that I can get the job done right. I want it to have some text on, maybe like now with 100% positive feedback or something similar - something attention grabbing but that speaks of my professionalism.

What thoughts do you have? It can be a little abstract but it MUST reflect the product I am selling.

If you can point to any examples that would be appreciated.

**After various requests, I want to point out I really do not have a set budget, I am looking to see the quality of work you've produced and for you to make me a proposal based on the work you produce**
