Startup Idea : The modern mentor platform

We know that we need a mentor in our live to help achieve our future goals, why not make a platform to easy touch with a mentor by category. If we need a business mentor we just find it on business category and we see their profile. And make it easy engage with them with some option like pay per question and pay per hour (using video calls). Understand that outside there already exist some mentor platform, but it still traditional way and expensive, let's build the modern platform and cheaper. If you are interested and want to contribute with this idea, let's work together.
