Change webpage a little

I have this webpage that needs some changing: https://www.cambriolage89.com/

cleanup coding so that I can modify it myself in the future
Force visitors to https
Change background photo to white background
Make text boxes a bit larger
Change font
Change js video player to standard html5 video player
Add a link for downloading the video
Add a link for sending e-mail
Optimize the headers for SEO
Other small changes I forgot to mention here because I didn't have my coffee yet

I will give you ftp access.

My budget is $20 maximum. If you bid higher than that, I know that you didn't read this text.
