Build an Online Store

I want to improve usability, aesthetics and design of [login to view URL] and sister site www.buffetgo.dk. These sites should be face lifted to same level as our competitor www.tgtg.dk. Main menu should be simplified to two selections List and Map. Scope is divided to two parts (1) Many small changes so that general visual appearance and shopping easiness are improved - All catalogs should appear in the landing page - Catalogs should be searched based on new catalog attributes, city and postal code - Catalog list view needs to changed to catalog map view where catalogs are located on map and can be easily opened - Mobile users can locate them selves and list view and map view shows restaurant only close to them ( is possible) - Background of catalog and product should be changed to appealing picture according to example from [login to view URL] (2) International scalability concept design and implementation - We need to decide weather to operate with one shopify accoint or one for each country. One account would be preferred but is it possible to provide different language and catalogs to each country domain? Solution should be easily uploaded or copied to new similar sites. - Our products are day dependant, We should automate current manual daily maintenance This is fixed price project, but please let me know you hourly price and workload estimate to scope described above. Please send referece shopify projects.
