Hello,
I am experienced web developer and I can surely help you with your website updates. I'm open to longer business relationship, and since I'm being European I can help you with creating new website for this market.
If you only know th FTP credentials for the website, you have nothing more to worry about. I can take care of all of those things within a week or two (the gallery might be one of the bigger obstacles).

UPDATE

Unfortunately I don't do SEO so I won't be able to help you with that, but I can add the responsiveness to you website, so it looks great on all kind of devices. The addidtional cost would be around $100 CAD
