Fix Issues With Wordpress Website

We need someone to fix several coding & minimal issues with our Wordpress website. The website is: www.jadetradinginc.com. Here's the list below. 1) HOME PAGE - Compare the quality of our version of the AC/Ocean picture to the one on the server. Seems the image quality is not as clear, if so then replace it with my high resolution version. 2) ALL PAGES - Center vertically the Contact form slider like you did on Ameri Temp. Seems there's a JS error that's not allowing it to slide out (only slides out on the Specials Page). Review that too. 3) ALL PAGES - Fix Fav Icon, it should be the red Jade logo, not the green one. 4) ALL PAGES - Center sub-menu text for PRODUCTS. Line Card & Olmo Mini Splits. 5) SPECIALS PAGE - Change the paragraph for specials so its not all caps, regular like all other pages. 6) SPECIALS PAGE - If you see it via mobile, all the pictures get all screwed up. You only see them partially. 7) LINE CARD PAGE - If you see it via mobile, all the pictures get all screwed up. You only see them partially. 8) INSTALLATIONS PAGE - Increase font of paragraph verbiage a tiny bit bigger. 9) CONTACTS PAGE - Make sure the footer snaps to the bottom of the browser like the other pages.
