This kind of work requires constant ongoing maintenance and improvement in order to run and create. The costs are relatively high and I do not have the resources available to cover them. If I were not being downvoted to zero, I would actually have the funds to start thinking about running such apps. The top 20 witnesses receive hundreds of thousands of dollars per year just from being a witness - setting aside their other projects. They also have a large say over what gets funded and doesn't get funded in the worker proposal pool. I suggest starting by asking them your question directly, since they are much better placed to help you than I am.
