Need help with Wordpress Website

I need help with my Wordpress Website. Several items:

1) Kit pop up takes up the whole screen on the mobile version and cannot be dismissed.

2) when I want to send a newsletter, I need to post it on my website, then copy paste it into Kit. I’m sure there is an easier way to do this!

3) My contact page is not set up.

4) I need to add a sample chapter and more reader magnets.

5) It’s boring and needs more help.

Who can I trust to help me?
