Hello uzairsyedahmed,
I think we can be of service at Blomstra, we have quite some experience with scalable hosting environments. The IAM authorization layer will probably need to be build on your behalf. Further continued support is not an issue at all either.
Let me know whether you have an interest, you can find me on Discord luceos#0001
or via daniel@blomstra.net
.
Daniƫl.
