Set up the most advanced Klaviyo flows

I've got a completely new Klaviyo account that I'm looking for a Klaviyo expert to come in and set up all the flows. I want the most advanced flows possible so I will like to understand your ability to deliver complex flows.

Apart from the general automated standard flows, I want you to create a flow that is based on selling to segments of our email list that specifically promotes a particularly item. More info on this can be discussed later.
