OpenCart, Wordpress, Theme Tweeks & Extension faults repaired

I have a theme template in wordpress for a retail business and am having the following problems I want to get fixed. The template is a: StoreFlex - Responsive Multipurpose OpenCart Template + RTL It is based in Opencart updated to 3.0 The panel I use is Plesk (which has all just been updated to work fine - Card Processing extension by wordpay - I cant get to work with the template - Opencart - Sales Motivator extension is not working correctly (it is meant to let you share the product you are looking at BUT it is only ever sharing 1 product (i would like this fixed or alternatively I would like it to share a link to the website page rather than the 1 product it actually lists if you share the page - - i would like a cookies accepted pop up so customers accept this when using the site - Cookies acceptance on website - OpenCart - I have a problem on the main page where the Products that are New in don't actually update with the new products we add to the site - Main page (New In Categories not updating with NEW in products ) under any of them - See Default section - Opencart - My main photos on the website in a banner are blurred (i don't believe it is the quality of the picture BUT more like its a banner that is not working properly and is stretching the images to fit pages (it seems to work fine when shrinking images for mobile us BUT not for wider screen use (Photos - Main Photos - Looks Blurry - Opencart). - I would like a large banner put across the top of the site aswell with the company logo (and the smaller top left logo not to show up - this would need to be compatible across all platforms I would also like someone to confirm if the SSL certificates are all correct and advise on any improvements going forward for the site. I am also looking for someone more long term that i can use for weeks and extension adding in the future as the website develops and possibly for other websites also.
