Shopping website like amazon

I require an expert guarantee. If you cannot provide one, do not inquire, do not bid. I will report you to vworker and they will deduct stars from you. As an employer, I do not get the expert guarantee. It is donated to charity if ever. I do not want my time wasted. 1. The website must be able to detect the country where the customer is, but the customer needs to be able to change that location manually. 2. If the person if from China, block the website. China will not be one of the billing or ship to addresses. Except if shopping from our HK store. 3. The website needs to detect the correct currency. Perhaps on the beginning of the page, we ask the customer what the "bill to address" is and what the "ship to address" is. So the customer can change it manually. "Please bill me in : "??currency??" The management needs to be able to modify what currencies are available. The customer also needs to be able to change these manually. 4. The customer needs to be able to view the price in at least 2 currencies. The default currency will be in bill me address, but they need to be able to change the currency manually. 1. Different reports for internal use and also for customer use. 2. We need to have an inventory capability. For example, item A, I can choose unlimited, only 5 left or however many there are, on back order, coming soon, not available. 3. Different languages capable. You will not be doing the translation, but choosing of language needs to be available if the need arises (this won't be for months or years). You just need to make sure that the website is capable of this. I cannot enter any more chararcters, just ask for the requirements.
