Make 18-20 minor design (and some other) changes to my wordpress website.

Hello there, I’d like to make around 18-20 minor design changes in my wordpress website (and also on an iframe I’ll be using in the website), so I’d preferably like to work with a web designer who is also good at wordpress. Most of the work has to be done in these 4 pages: A: [login to view URL] (home page) B: [login to view URL] (listing page) C: [login to view URL] (iframe) D: [login to view URL] (product page) Here are the individual changes to be done point-wise: 1. Change the permalink of the wordpress website to /%postname%/. I’ve tried it but all is see is 404 page afterwards. 2. In the Products page (A), the “test drive” button has to be shifted to the right. 3. In the Products page (A), the sticky top menu has to be converted to full width. 4. In the Listing page (B), decrease the width of the left sidebar as to increase the space for listing area. 5. In the Listing page (B), the car-listing has to be changed to look something like this: [login to view URL] (mainly the product image has to be rectangle and distance between the products, etc). Also the height of individual products vary, which has to be fixed. The heading has to be truncated in case the title is long. 6. In the Listing page (B), the appearance of filters has to be changed (just the basics). Also background color has to be changed from white to others. 7. In the iframe (C), the four buttons (doors opened, doors closed, etc) do not show in Mozilla firefox. 8. If the iframe is opened individually in a mobile device, it is responsive, but when the same iframe is embedded in the website, it doesn’t look good in mobile. (Check links ‘C’ and ‘D’ in a mobile device). This has to be fixed. 9. In the home page (A), (only in the mobile version), there should be a sticky button sticking at the bottom saying “find my next car”. Sticky button something like this: [login to view URL] 10. In the products page (D), (only in the mobile version), there should be a sticky menu (just like the 9th point) for “test drive” and the test drive from the top sticky menu should be removed. 11. In the home page (A), in the “choose your car” section, hovering over any of the four car silhouettes should show a brighter version of the image. 12. In the home page (A), the thin white line between the logo and the blue top menu should be removed. 13. The pricing commas has to be changed to the Indian system. 14. In the listing page (B), the “buy it now” button has to be removed. 15. In the whole website, the main header (logo+menu) takes up too much space. The height has to be reduced. 16. Install and set-up “YITH WooCommerce Compare” plugin and set up. 17. Add a horizontal bar (something like [login to view URL]) just below the sticky menu on the products page (D) which won't be sticky. This is the basic idea. We can maybe do some minor modifications while the project and the discussion continues. Thanks for bidding in advance :) Note that copy-pasted proposals may get a little less preference. Thanks Again :)
