Migration of existing html site to Wordpress

We need an experienced person who can move our existing website ([login to view URL]) reliably to Wordpress. The new Wordpress site should be based on the theme "Persuasion" by "Mysitemyway", because of its excellent design and important features such as responsiveness. In the new site we must be able to insert image sliders anywhere. This is readily possible with "Persuasion". Colour scheme of existing site is to be maintained. The home page should not have any pictures except the company logo (same as now). Product information in the site is currently grouped into 3 categories of brands (manufacturers): Modern, Classical and Minotti. Within each separate category, the various brands must be ordered alphabetically. If we enter a new brand it automatically fits into the correct alphabetical order of brand names. Whereas the current site features more or less static information for each brand, in future we will be posting additional current information about each brand frequently, including pictures which will be mainly presented in sliders. Other dynamic posting areas are "News" and "Events". Posts should be ordered chronologically. "Events" can be announcements about future events or reports about past events. The other pages of the current site contain information which is static (i.e. rarely modified) and will remain static in the new site. Looking forward to your proposals, Rainer
