How about a "bring-your-own" GPT-3 API key SaaS?

Hi all, Someone should build a SaaS where clients would bring their own ApenAI GPT-3 API key to generate content for themselves. I have an API key, but I'm struggling to find a trustworthy developer who can build an app for me. I'm sure there are many others just like me who would be happy to pay someone for a ready-made solution where they can use their own API key. Does this make any sense?
