I need a travel photography website

I'm looking for clean, simple and professional looking website to showcase and sell my travel photography. Both mobile & desktop friendly. I would like to have albums to showcase the different categories of photos and be simple for me to add more photos. Also to be able to select deferent sizes and pay for them securely via PayPal etc.
I havnt bought a domain name yet but can straight away.
This will be my first website so any ideas or input from people who have done similar projects would be great.

Thanks

James
