Django Project Management Company

Hi All

I’ve been volunteering on a charitable project

The site is doing great and everything is going hunky dory. The site is a standard django/DRF/wagtail with a sprinkling of react.

My question is about long term maintenance and that not falling into my shoulders. I am looking to engage with companies that offer the service of maintaining/hosting the site and also be able to do some adhoc development where required. Does anyone know such companies? How much do people pay for such a service? Ideally I would like an established company with more that one developer?

kind regards
