Need Shopify developer to make some changes and speed up my Shopify store

I need a Shopify developer to help with a few small changes to my site that I don't know how to make, and also speed up my Shopify store so that it passes all PageSpeed and GTMetrix tests and ultimately loads fast on every page. My store's URL is PassionGear.net. Here's the list of changes I need: 1. Site needs to be fully optimized for speed so it passes all PageSpeed and GTMetrix tests. All grades should be green or as close to green as possible and every page should load as fast as possible. My guess is that there is a plugin for this kind of thing. 2. When you click on a product page, it shows like 5 different drop-down/radio button menus and then loads the proper 2 or 3. I would like the extra menus to not load at all, I have a feeling it's slowing down the product pages. 3. Contact page needs a couple of corrections. --The submit button needs to say "GET IN TOUCH" instead of GET IT TOUCH. --Instead of "We can help you?" it should say "How can we help you?" --Instead of "Additional Detail" it should say "Please briefly describe what you need help with." 4. Need to get rid of the scroll to top button. 5. On the FAQs page, at the bottom, I'd like to add some space below the Contact box so it's not right against the footer. The space should be the same amount of space that's above the box. So mostly pretty simple changes and then optimizing the site to load as fast as possible. I'd be willing to pay for a premium plugin/app that will help get the job done.
