Fix Margins & Resize Images on Shopify Site

I recently hired a freelancer to convert my site to Shopify; however he refused to complete my website as he lacked the skills necessary to adjust the margins between the sections on my pages. I have attached an image to this project showing exactly what I need done on ALL Information Pages of my site. Some of this work has already been completed (most text and images are aligned to the side margins), but some is unfinished. My site has about 14-15 informational pages where this content needs to be adjusted. Again, some of it is already done, so please review the site to see the fulls cope of the work: [login to view URL] I need margins put in place between various types of sections as you go down each page on my site (between text/image sections, strips, quotes). I need images and buttons properly aligned within each section and the "invisible" margins on the page, which I represent in the attached image with pink dotted lines (these dotted lines will NOT appear on the site). Aside from fixing these margins there are a few other little things I need assistance in fixing, such as resizing a few images (less than 15 across the entire site) that are incorrectly sized (affecting the image quality), replacing a one or two paragraphs of text on a couple of pages, and making sure all the internal links are connected correctly (we will do this together one page at a time). These other fixes shouldn't take more than a few hours. All in all for a developer who knows what they are doing, the margins shouldn't take more than a few hours to adjust, and after that the other small edits we do together should take another few hours. I don't think this project should take more than 8-10 hours at most for someone with a good skillset who is proficient with Shopify.
