Hey, I'm very security and privacy-focused, so I could probably help you when it comes to advising hosting providers, scaling and stuff. At the moment I'm not actively looking to freelance due to lack of time, I just wanted to let you know of me in case you need trusted advice concerning this particular topic, so you have someone to reach out if such need arises 
In the past I wrote fairly lengthy opinions about hosting solutions, so you can see I know the subject reasonably well
