Copywriting

I need a quotation for reviewing my current website [login to view URL] and making necessary changes to its content, including correction of spelling, grammar errors as well as generally putting its current content into a nicer way, so it sells better (excluding Privacy, Terms and conditions and Site Map). If you are also specializing also in website optimization (so all the content and buttons are where they should be), please quote me with this service separately. ( I mean not for making the changes but only for suggesting a proper layout).
