website needs final touches before going live

i have a domain, bluehost paid for, and wordpress is installed and I have chosen the theme but I dont know if it's really what I need. my website is learntogrowplants.com it will be a blog designed to act as a landing page so I can redirect to affiliates. I will be writing blog posts about different ways to propagate plants and how to grow a backyard nursery and supply it with repurposed materials. I will have articles about different sizes and kinds of greenhouses to meet different needs. Basically, that's the plan. I just dont have the knowledge or time to learn and how to set this all up. #1. i need email marketing set up. #2 I need a gallery set up for photos of my nursery and #3 a link for my youtube channel and Im pretty sure the theme came with woocommerce and I need to get a page set up to sell my dayliliies. I'm having to charge way too much on Etsy for my daylilies and at any moment Etsy could wake up one morning with an attitude and delete my store for no reason and I cant take that chance but right now its the only thing I can work with right now. I would like to build a trusting relationship with someone that can help me start making enough money to where I can hire them steadily to keep my website seo optimized and youtube seo optimized because I want to focus on the unique content I have to offer as far as articles and videos. I KNOW I have a brand that is going to be unique and profitable but I need help.
