I’d like to make changes on this template :

I need to change colors to red and make 5 additional subpages, witch gonna work like „smooth scrolling”.

Create webpage by using WIX

I would need assistance to create new website for my company by using wix.com templates. Should be 3-languages, including blog and chatter functions. Current page I have done myself but my skills & time are limited so would need a pro to help!
