Payment Gateway for UK Dropshipper


Hi Guys,
I have set up my drop-ship store, have around 400 items, web-store all corrected (description and pictures etc.), and now I am ready to begin with promoting my website. But, before I can do that, I guess I need to set up my payment gateway. Since I am in the UK, plus I have PayPal connected to my credit card, what other payment do I need before I actually begin? Do I need to upgrade to a PayPal business account before I can begin?
thanks in advance.
