Mens Fashion Sketches - Underwear brand

I need drawn (digital) sketches for a mens underwear brand. The idea is that you have a sketch of a fashionable man (similar in design and style of the attached) and then you have exactly the same man (in the same pose) but only wearing my new underwear brand. Background designs should be various locations around London. In total I need 10 sketches (5 will be the fashionable man dressed up and the other 5 will be the same fashionable man but wearing the mens underwear). Examples of work is required. If successful I may need more than these ten sketches.
To be awarded this work I will require a basic sketch illustration with the reply to ensure you are capable to draw illustrations in a similar style to the attached.
