Artwork / Watercolors for website background

If you go to [login to view URL] you will see a website background in "water color" style. I would like a similar background for several own websites which are job portals relating to different locations (Asia, London, New York, Dubai, Hong Kong, Singapore, China, Australia, international). The artwork should be a mesh up between scanned water color painting (for the sky) and some additional elements (similar to the clockwork elements on the original websites, but please do NOT use clockworks). If you can come up with some ideas along the lines of the above website that would be ideal. The common theme of the job portals I am trying to build are "law, lawyers, jobs, finance, corporate" and then each portal has a geographic focus (as described above). Ideally we will start with a potential wallpaper for a portal called "London Lawyer Jobs" so you can show off your skills, and if I like it then you can do a whole series of up to 20 additional backgrounds with other themes. To be considered for this project please provide some sample artwork you have created. Ideally you could show some artwork involving water colors / mesh ups but it is not a must. Final deliverable should be a Photoshop image. Thanks. Budget for the initial background 50 USD.
