Ongoing maintenance and development of Magento 2 shop

We're looking for an experienced Magento developer to help with ongoing upgrades and bug fixes.
We currently have a live site www.lampwise.co.uk and a testing site.
We need to have a working relationship with a developer who can respond and resolve issues quickly as they arise.

We have a GitHub with each issue listed, some issues we have currently are:

1. Updating a module to the latest version on our live site and push to git
2. Installation of a new module to a test site
3. Bug fix an issue with 3rd party module

Point 1 is urgent so would appreciate a quote for this asap.

We can then discuss the other issues and a rate for ongoing ad-hoc work.
