Need Specific Advise on Amazon

Hail Warriors,

Here are a couple of things I already have -

1. A domain-name already registered. It was supposed to be a apparel/fashion store, but the entire plan could not work out due to supply-chain issues. So the domain is sitting idle.
2. Wordpress hosting from GoDaddy, for the same purpose as above, sucking $10 each month from my credit card.

I've been looking for ways to monetise these investments.

Now there are several amazon affiliates around such as wirecutter.com and others.

I am seriously thinking of becoming an amazon affiliate, in specific fashion & apparel categories. As far as work is concerned, I am ready to put in hard-work on development of front-end as I have good experience in Web-design. The quality I desire for my store is top-notch, something like wirecutter has.

However, the advise that I require are as follows -

1. Amazon has tons of thousands of products in fashion/apparel categories, how do I go about automating or at least expedite the process of displaying the top ones on my storefront.
2. Are there any tools/plugins available which would enable me fasten the entire process.

Regards.
