pre order sale

I am looking for help with my pre-order sale preferably using Shopify and the Ordersify app as I already have and use it. I'm creating a physical product and will be running a 2 week pre-order sale. I'm a bit new to the marketing side of things, so I would like to have someone teach me how to achieve optimal results. This project is focused on getting someone to help give guidance and advice on how to set up the pre-order sale. Advertising experience is preferred. The end goal is to have full knowledge of how to set up a pre-order sale and generate as many pre-orders as possible and reach maximum exposure. If you think you are up for the challenge, let me know and I can discuss the details with you!
