Small Customization in Variation in Woocommerce Products

I have woo commerce website that has variable products. The variations needs a small customization in terms of design/visuals but it may need to customize the variation plugin/theme to achieve the goal.
here is a product page of my site with variable product
My Current Site:

Cadbury Dairy Milk Silk

What I Want to Achieve :
please follow the attachment,
1. The variation prices should be beneath the variation button for each variation
2. The Per gram price should be also there as per the screenshot.

I will provide the example site URL to the final candidate.
The current task is small, but successful implementation may lead to a larger scope of work.

Thanks,
MD
