complete the project - updating website www.sudafrika-wohnmobile-und-camper.de

this project has previously been assigned to another freelancer who was unable to complete it - I have his permission to pass on the work he completed so far, for someone else to complete. the original job request was to update [login to view URL] , new logo, modern, clean look, mobile and SEO friendly and incorporate a system which will quote prices for rental vehicles. This "front end " is 90% complete and just needs some minor changes - see [login to view URL] If the new freelancer wishes to change things (color, layout, image) to give it his "personal touch" that's fine. The "back end" is the part that will do the quoting - this is the part he found difficult to implement. He came up with this dashboard [login to view URL] Which will work great but needs to be set up correctly. I am looking for someone to complete this project as soon as possible. I am happy to assist (uploading images, entering rental rates etc.) The quoting/ pricing is a rather complex as we are currently dealing with 4 different rental companies in South Africa and Namibia, the rental rates they stipulate are in ZAR/NAD we add our commission and quote our customers in EUR, each company has their own rules and seasons. All rentals work with Seasons (lower rates in off peak, higher rates in peak season) They also have charges depending on locations - for vehicles collected in Johannesburg need to pay a toll fee. Previous experience of implementing a rental quotation system would be great.
