Around 25 minor design and functional changes to my wordpress website.

Hello there, I’d like to make around 25 minor design and functional 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. Broadly, the works include many wordpress design changes, one plugin compatibility, and some small tweaks to an html iframe snippet. 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) Note that changes has to be done in the child theme so that future theme upgrades don’t hamper the design, etc. Also any changes should not brake the responsiveness of the website. Any suggestion by which we both can save time is welcome. 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 Listing page (B), decrease the width of the left sidebar as to increase the space for listing area. 4. In the listing page (B), the car listing is completely unstructured and following changes are to be done there: a) Only three cars per row. (Nothing to change here). b) The width and height of each image has to be fixed, and has to be rectangular, irrespective of the dimension of the images uploaded. c) Currently the height of each item differs and depends upon the content written. This has to be changed and height of each item has to be exactly same. d) Sometimes, the height increases because of the long car name. This has to be fixed. If the car name is long, that has to be truncated. e) The design has to be converted into something like this: [login to view URL] f) It does not have to be exactly like above but the font size, color, etc. can be taken from there. g) A third row can be created to add the price of the vehicle. It need not be overlayed as shown in the screenshot above. h) No need of ‘add to compare’ button. 5. 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. 6. In the iframe (C), the four buttons (doors opened, doors closed, etc) do not show in Mozilla firefox. 7. 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. 8. 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] 9. 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. 10. 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. 11. In the home page (A), the thin white line between the logo and the blue top menu should be removed. 12. The pricing commas has to be changed to the Indian system. 13. In the listing page (B), the “buy it now” button has to be removed. 14. In the whole website, the main header (logo+menu) takes up too much space. The height has to be reduced. REST OF THE POINTS ARE ATTACHED IN THE TXT FILE BELOW: Thanks for bidding :) Note that copy-pasted proposals may get a little less preference. Thanks Again :)
