Just present an audience with a list of service providers, and they’ll take care of the rest.
One good option for finding affiliates would be working with an Affiliate Recruitment Agency. These agencies differ from typical Affiliate Management Agencies in that they focus entirely on finding and recruiting affiliates for brands.

Ideally, you should only create product reviews for products that have the potential to sell in high volume; even better if a lot of people are searching for reviews of that specific product (once again, use SEMrush to perform your keyword research). Otherwise, you’ll be spending too much time creating content that won’t result in enough sales.
As I mentioned just before, each affiliate program has its own specifications on how they pay you and what constitutes as a commission; as for how you actually make the money, it depends; however, these are the most popular payment plans for affiliate marketers: Pay per sale – this is the most popular form, which basically means that when a visitor who comes from your site buys the product/service, you get paid a percentage of that sale (the percentage differs based on each affiliate program); and with recurring affiliate products, you’ll make a monthly commission as long as that person stays a customer (or for a set period of time)Pay per click – as the name suggests, this means that you get paid for the traffic you direct to the merchant’s website – great if you get a lot of traffic alreadyPay per lead – this method requires that you direct people to the merchants’ site and you get paid a commission when the visitor takes a certain action (for example, completing a form or starting a free trial)
