Copyright, creative writer, designer, UI/UX

I have a new idea for the holiday let industry and have 2 or 3 websites in other industries doing similar type of market place and would like someone to create me some wording, phrases, strap lines, content for about, how it works. I almost know exactly what want already but want 2nd opinion and review by professional who’s been involved in successful websites / apps to make sure perfect. Will include social media adverts which I think will mainly be targeted ads on Facebook.
