Help with the Colorway theme

I would really like to have someone, who can work on this, because I do not want to make a mess out of what I already accomplished.
I hate my store layout. I am told it is because of the theme. BUT this theme is very conducive to my needs. I have not found a theme that caters to old ladies computer illiteracy.

Here are the BIG: Things that need to be fixed, which really do not take much time, if you know CSS:

My Download button should be prominent , BIG and working after payment.

My “Buy NOW Button” should be on the TOP next to the listing picture on the Webpage. My “ADD to Cart button” on the bottom of the listing page.

My picture sizing is put in all the same but shows up different sizes randomly.

When I share my page on social media I get this blob picture. To autopost I need it to work with a picture of my patterns.

My Bing codes and Yahoo API code need to be fixed on there. I have not gotten those codes, because they want my cell phone and I do not have a cell phone.

A sign up widget to follow Blog. NOT Jetpack, since I do not like their advertising.

Newsletter uploaded. Have a problem with the Zip drive.

Child theme stabilized. It craps up and makes 404 errors.

The share icons are often weird looking ( distorted) and also there are share icons double: the distorted ones and the real ones.

HELP please
