I need a website for my shoe business -- 2

So my business is Basically about Sneakers . My Business targets Mainly african countries (zambia, Botswana, Malawi, South Africa) I want an app that allows people to pre-order their sneakers, These sneakers are not readily available but they have to be shipped out from China To the desired country. I need an app that Gives my customers a platform to browse through and be able to see what’s in stock, also to make payments and be able to get notifications or updates as to how far their order is going till it arrives desired pick up point.
