Small redesign of the site

Hello, there!
There's a website.
The following corrections must be made. I'm interested in price.

(1) A horizontal menu bar at the top of the site is needed to be always on the screen when scrolling.
(2) Remove the background images from remnants of old images, overlays, etc.
(3) Top picture - there is a lot of empty space at the bottom. You can’t cut off your legs – you need to reduce the picture.
(4) A wide side screen produces a void. Make a smooth transition into a black background? Or should I look for a new picture? We'll replace that background with ours later.
5) the application has a slightly modified layout: added menu and reworked the section on crossfit (background man with ropes). The background was not cut “under the arrow” – I show the principle of the location of the text. If you need to work it out, tell me. (Makeup – 文本隐藏)
(6) The video from the first class is for the time being deleted. When we do, we'll add it.
(7) Repeat the section "Why Crossfit 394" Text attached.
(8) Fill in the “Important issues” Text attached.
(9) No mail from the feedback forms is sent.
10) Link to social media icons
