Ongoing Maintenance of 2 Woocommerce Websites

I have 2 Woocommerce websites which are basically the same but one has GBP as the currency and the other EUR.

I am looking for someone to make sure that updates to Wordpress, Woocommerce, PHP and plugins are carried out without breaking the sites. This includes Stripe and Paypal integrations.

This would be on an adhoc basis with the initial project being to ensure that the sites are up to date.
