Need Shopify developer for a few changes to my store

I need a developer for a few quick and easy changes/fixes to my Shopify store. Here are the details: My store's URL is PassionGear.net. 1. I want to add the "Trust Footer" from the Home Page to every single page on the store. So the product pages, collection pages, about page, cart page, contact page, etc etc. Every customer-facing page should have this trust footer. Refer to the screenshot labeled "1" to see what I mean by Trust Footer. 2. It may be just me but if you go to a Collection page on Mobile and try to use the "Browse" menu... If you click on something in that Browse menu, it doesn't work and it doesn't filter down to whatever you click on. I need this to be fixed and functional across all mobile devices. 3. On Mobile, you can't scroll through all of the Product Images on a Product Page unless you attach each photo to a different variant. Well, some of my products only have two variants and four photos, so I don't have enough photos to attach it to. I need this problem to be fixed and allow mobile users to scroll through all the product pictures regardless the number of variants. 4. I have Apparel and other products on this store. The theme was setup for a T-Shirt store. When I setup a product that only has one "Option" like the type of Phone they have, I am forced to add two extra Options for Size and Color, even though these extra options are not necessary for the order process... Please refer to the screenshot file labeled "4" for a reference of this issue. I want this fixed if possible so that I can list a Wallet Case or other products without having to add any unneeded options. 5. There's a little extra space between the end of the content on the About page and the footer. I would like some of that extra space taken out so the page looks normal. 6. Same thing with the Contact page, take out some of the extra space between the contact form and the footer. This is not a big project, I know what it's worth, and I won't be paying a whole lot for it. But I will use you in the future for more work if you do a good job. Please do not quote over $100, as your proposal will definitely be discarded.
