estimating costs for website development

I need a web developer to code a similar website as shoesofprey.com, getwear.com. Basically all features are those that every online shop has (shop, about, contact, faq etc.) but with a 2 d designer (shoesofprey uses a 3d designer).
I am not a coder or anything close to that, so it would be more than helpful to understand if this sort of website is considered to be a large project or medium in order to know what costs I can expect.

Any suggestions are appreciated!!!


Thank you!!
