Wordpress maintenance

I'm looking for someone reliable to regularly update our Wordpress website. There are always things that crop up, and unfortunately we also have a backlog of issues that need fixing (SSL certificate error, new theme update). I particularly want to work for someone who responds to my emails in a timely fashion and gets the work done by mutually agreed deadlines. Sorry if this sounds a bit harsh but I've been let down by two different admins now, who simply disappeared at inopportune moments.

Please contact me if you're interested in this ongoing revenue opportunity.
