Hello,

You need to hide the actual price and add to cart and variations from the single product page. For the variations you can simply remove the variations from the product edit page, variations tab.

To hide your required items you can use the below CSS code in Theme settings>> custom CSS >> global custom CSS area.

.single-product-page .product-image-summary .summary-inner>.price{
display:none;
}

.single-product-page .variations_form.cart.variation-swatch-selected {
display: none; 
}

Also I suggest you to use the grouped product type, because that product type is very similar to the view which you want to achieve.

Result of CSS code which I have provided you above to hide those items: https://jmp.sh/qOD5u6Q
