No problem. A few services have tried this concept (and some of them even employed blind people as the human readers), but none of them took off. Reading outloud is rather difficult; it generally takes 3 minutes of time to record every 1 minute of audio, because of things like editing and correcting mistakes and so on. People who can quickly, reliably, read text aloud tend to get well paid jobs as audiobook narrators for companies like Audible.com. So most "web page reading" services generally go out of business, because people aren't willing to pay the actual cost to have a quality reading. And a text to speech reading is almost always better than a poor quality human reading. The most notable example of a service that went under is Umano. It had several hundred thousand users, paying monthly.

I'm sorry for coming off so negative, and I wish you all the best of luck! But I hope you've done your research into previous businesses like the one you're trying to launch, and have come up with new ways of avoiding the pitfalls.
