Need help integrating checkout to my webpages

hey guys!, I’ve been stuck at this problem for a few weeks can you guys help ???
I want to integrate woocommerce subscription method on my website.
Im selling a service for an ecommerce solution. Hence i have various packages which i want to sell.
Now i want to add buttons to my packages webpages (Not using shop page). The button should redirect them to either the checkout page or any gateway where customer can enter billing information and buy package.
You can visit website to see exactly what i mean. The link is tirebiz.net (Website is still underconstruction so somethings might not work). I want to sell a service. Hence the product is virtual.
I can’t see to be able to add a button to my pages after which the customer can fill out a form and pay for the service. Can you please help with my problem?? ??
