Prestashop Expert for Template development/modification

Hi, we're looking for a reliable experienced Prestashop developer. Our need is to develop a highly customized Prestashop site. Our designers created a custom graphic layout based on a responsive theme*. In agreement with you we will define the best solution between: -Direct customization of the existing theme (that we will provide). -Creation of a custom theme from scratch (in case you consider it easier and more stable). Please consider that our designers added two modules (News and Forum) to the original theme, which will both have to be consistent with the new graphic layout. Feel free to ask for further information. *Responsive theme details: -vertical mobile version (320px) -widescreen mobile version (480px) -Desktop version. We attached a compressed file which contains the template screenshots, a document with specifications and the link of the base template.
