I've been thinking about starting a similar service based on requests from clients for various types of monitoring.

Seems like there is lots of competition. And I'm not sure this is an aspirin or a vitamin. http://www.startupsfortherestofus.com/episodes/episode-92-12...

But if it's specialized and at the right price provides the right value then why not?

There are lots of services out there bringing in $100k/yr that are niche and even when seeing their shared revenue numbers I'm always surprised it's possible.

If it's something you enjoy working on and think you can market it go for it.

Looks like you're building this in PHP, check out the Laravel Framework, cashier is built in for connecting with stripe, Spark ($100 per major release) is close to SaaS in a box, checkout homestead/valet for local dev, and forge for server creation/deployment. (if you haven't already).

Good luck, keep us updated.
