Urgent Shopify Theme Customization

I urgently need a proficient Shopify developer who is experienced in theme customization. Here's a brief overview of what I am looking for:

I would like some customization on my Shopify theme.

My home page menu items need to show relevant products when clicked.

The text on the product thumbnails needs to be slightly bigger. Please discuss with me how I want it to look like.

I would like to include an Instagram reel at the bottom of my main page. It should be a free app, so I don't have to pay them monthly.

I also want to include a section for TikTok videos at the bottom of my main page. It should be a free app, so I don't have to pay them monthly.

I also need some minor adjustments in the footer area so I can make the description in the footer slightly bigger and make everything look perfect
