Squarespace/Wix Website Designer for Photo/Video Companies

I have a few different businesses I need updated websites for.
Please read the full description to see if you are a good fit.
My businesses are all photo/video production agencies in the US, each within a different niche.

I am looking for someone that can design multiple sites and also include a 'portfolio' page, case studies page, contact form, 'about' page on each site.
Most likely via Squarespace, but I am open to Wix as well. It must be something I'm

The 3 sites are already live. Here they are:
www.diamondcutweddings.com (just need updating)
www.jcreativehouse.com (need brand new site)
www.jakesvisuals.net (need brand new site)

I will only consider applications that:
- are experienced in Squarespace
- say "Square" in the application subject line. I need to know you're paying attention :)
- include links to previous sites you've designed

Bonus points if you have basic SEO knowledge as well and can implement that into the sites.

Ideally, I am looking to hire someone full time for one month to complete this project by end of January.
