Graphic design work for 'cost of living' graph

Please see the attached graphic below. This is a draft I have created. I need a PROFESSIONAL to work their magic on this to make it look as sharp possible, the graphic is going on the wonga website and it needs to match the style and brand of the rest of the site.

Please contact me with relevant past examples of your graphic work currently hosted on websites as well as your required fee for completing this job. Any questions needed please ask!

Thanks,
Scott
