Redefine your MVP to something you CAN build within a month. It probably doesn't need all of the features you envision in your mind. Engage the users you already have and give them the bare basics to get started and let it grow organically over time. Choose languages and frameworks which will let you build this fast and don't worry too much about performance or scalability till later.

Maybe also try to get some help from the community there is already some excitement around your product.

But if you can finance it, hire a programmer.
