You’re too busy to find a design for your own client?
Anyway, pretty much any business theme on here with a slider that has a custom control panel, color schemes, and claims to be highly customizable will be suitable for something like the site you listed.
Just by taking a (one of the many) business theme and changing the background, navigation, logo, and images on the page, you should quickly get a site that looks similar to the one you listed.
we find the theme and you got the commission for this work?
you seem to be much more clever than anyone else here (:
get the time… no offense but the authors here do all the theme work, with all the guidelines and documentation on how to use their themes … you just need to search 15 minutes for a proper theme.
