Web development

I need a new website. I need you to design and build my online store. We are a company producing and packing Honey for the local domestic and export markets. We have found some success with our current website but would like to move forward and start really making some headway. Ideally I would like a user login where each custome4 can revive a tailored experience for example Wholesale customers can see different pricing on inventory items or more specifically individualised pricing. I would like the general public to also log in as a user and take advantage of discounts and loyalty bonuses, All login users would be able to see previous purchases , repeat favourites , have suggested buys based on past history, reminders for repurchasing ,reminders for wholesale customers for scheduled delivery dates. Will also need apps. App would have options to simply scan barcodes products add required minimum order and send to us as simple as possible to make their life easier . Reminders that if you order less than a full carton you get discount to increase quantity... etc We need to see purchase history and be able to report on sales and margins. The inventory would be a single product with 4 variations of pricing and be displayed and applied to different logins , ie retail wholesale export specials Invoices would need to be generated as well as packing lists So orders could be traced from receiving order through to delivery. We currently use xero as our accounting so integrating with this would be great . As some of our clients or abviously on account .
