Webmaster needed for website refurbishment

Hi. My name is Marianna. I have a full time jobjob my passion is photography.
I have had my own website on WordPress for many years (www.mariannastefani.com) but now I need to step up and make things work smoothly.

I would like someone to help me switch seamlessly to squarespace in terms of hosting, mail management etc. I will take care if the design because I am picky but input on that will be appreciated.

I will then need help with maintenance every now and then, like speed optimisation and SEO, and also I will need to link all social media and find a strategy to make my work more visible.

I intend to sell prints so I need someone with a bit of e-commerce knowledge (I will most likely use third party companies like redbubble in the beginning)

As I said I have a full time job and I will keep it, I therefore have limited spare time to dedicate to this, but anyway I am not in a rush.
I hope I can find someone to work with who understands my needs and patience enough to explain me the process we will go through.
