There's probably a $30/month tool that solves your problem. Let's find out before we build anything.
We have an obvious financial incentive to recommend custom development for every problem that crosses our desk, and we try very hard not to let that incentive do our thinking for us. There is a SaaS product for almost everything now, and many of them are surprisingly good. We would rather spend an hour helping you evaluate existing tools than spend four months building you something that creates permanent dependency on us. This is not generosity. It's self-interest in a longer time frame. The clients who trust that we're honest about build vs. buy are the ones who come back when the problem is genuinely worth building for. And those problems are genuinely more interesting anyway.
