Amazon Store Advice?

Hi Guy's

I'm going to be building an Amazon Store with a web developer friend of mine.

We've picked the niche and we're going high end. Products start from $20,000 and go up to around $118,000 so we're pretty excited.

Anyway, I'm looking for a bit of advice because exactly how we're going to build the store is going to be our main concern.

We don't want to use an Amazon store builder software because the look of the stores look a bit 'budget' (not to sound like a snob) and they don't reflect the type of products we're selling.

Also, as they normally just pull all the data from Amazon and we don't want to get stung for having duplicate content we'll probably have to write the product descriptions manually.

So I suppose my question is, what sort of things can we automate?

We want to make this project as easy on ourselves as possible and the thought of selling the site later down the line is also in our minds. We want to make it as easy as possible for someone else to run the site.

Another issue is having people come to our site, see a product, want to buy it and it being out of stock with the vendor.

Any suggestions?

Thanks
