I'm CTO at one of your target firms. Integration is a major pain point for us. We don't have a need for you now, but I've noted a few things based on what I could find on Alstonia.io. My needs are different than others, but hopefully this helps. If any consultant or agency wants someone like me to hire you, I want to see that they have used the tech we use, that I can estimate your cost reliably, that they're reliable people in general and that I can understand the code they write. The stuff about security and high availability/fault tolerance kind of comes as a matter of course.
You can check a lot of those boxes by 1) some content on your website describing previous projects (like whitepaper PDFs or long-form blog posts), 2) GitHub projects, 3) references/testimonials. Then give a giant call to action form including asking for a phone number (I hate giving out my phone number, but it seems like everyone requires it, so I imagine it would help you more than not).
Note that these needs are very different then what I'd need from an employee. For instance, I can invest in employees and give them time to learn our tech. For consultants, I can't.
