Webmaster & Internal Tech Support for small online company

I'm looking for a web developer to help me move my WordPress site to a platform like Kajabi or similar all-in-one platform like Go High Level, move the email automations from my current system to the new platform, and then also support me and my small team with various tech support like setting up new software or apps, work flow automation and incorporating AI, various site work when it needs to be done for new product pages, sales pages and funnels etc. Not creating the content, but the tech side of things

This job is long term and will start off 20-30 hours per week but then move to more of a maintenance mode (5-10 hours /week) in a few months after the main migration work is done.
