HTML, CSS and Javascript developer needed

Hello! We need a front end developer to update the design of our platform. The code is ONLY HTML, CSS and Javascript. This is NOT wordpress or any other CMS and not PHP. There are 12 pages in total. Some page have simple changes like change button color, center text and formatting, some little more complex. You just need to change the design not build functionality. Design should be responsive, as long as you just update the design everything should work fine! We estimate a page should take you 1-3 hours. Pay is $300 for all 12 pages. Looking for someone who can start this week and have the first 3 pages done by Monday. please note and in your job application we would need you to confirm the following are ok: 1. Pages/designs will be shared as they are made. We don't have all the designs to show you at once. It's not very challenging work. If you're good, it should not be an issue. 2. You will be working on our cloud server and have to create a cloud account (its free) to work on the code 3. You will have to sign an NDA 4. We don't have PSD files. Some pages have jpegs, other times we will just explain. We may also provide github links to opensource code you can use e.g. for icons/toggle buttons 5. You must know how to use Github (pull, push requests). 6. You must know HTML, Javascript and CSS That's all! Thanks!
