How to bypass the product cart page and get a link directly to the checkout page

Hi folks,

My site, toursincolor.com offers its visitors different tours to book.

Since my site is marketing a service that only requires one transaction, I'm hoping to bypass the cart page that squarespace requires, and go directly to the checkout page. For someone who has no background in code, is this relatively doable.

If this isn't simple, then I'm open to some alternatives. 1) Get a direct link to the checkout page that I can email customers or 2)  Get rid of the quantity in the cart page?

Thanks for all help in advance!
