Redesign of an Web interface and few Email templates

A reservation system which is built 5 years back now need a facelift. A professional UI/UX developer who sketch the designs and do few rounds of optimizations with me based on mine and my clients feed-back is what I'm looking for. I will be giving access to the existing system, the areas we need to improve along with the list of new additions. Responsive with web, tablet and smartphone. The work has to be delivered with all source files (sketch, Marvel, PSD,AI etc) and converted to HTML5, CSS3, Javascripts. The work/project can not be used for marketing purpose or in portfolios.
