Remove add to cart @ WooCommerce with Tshirt eCommerce

Hello guys!

Uninteresting information ?? :
I’m kind of new to WordPress and all its features and modification abilities. Couldnt find any simmular post somewhere on Google, my friend, so I need some help for beginners.

What I actually need help with:
I am using WooCommerce with Tshirt eCommerce plugin and have some products, on the page I am creating, which NEEDS to be customized before adding to the cart. The thing here is that there is an “add to cart” button on the first page under every ptoduct and on the product page and also a price. If I keep the price field empty, when creating the product, it says when logged on as a customer “Please add price for product”. This doesnt look to good and professional. Also one important thing to keep in mind is that on some products I will need to have prices and add to cart button so I can not remove them from everywhere. The price thing is not as important as the add to cart button. I would like to have a customize button instead of an add to cart on those products if that is even possible.

I don’t want to install 100 plugins to the page, I prefer codes that can help med modify the things I want. I have some knowledge in coding but still I am a newbie. ??
