I'm in a similar position. I was accepted to Founders Institute but probably will not attend.
I decided to code the prototype myself. In a previous life I was a developer and it has taken me the past 9 months to get back into coding and learn new languages that I'm using for the build. I definitely advocate learning to code but you have to realize that this route is hard, time consuming and requires the ultimate commitment.
Finding a developer in the Bay Area willing to jump into an idea on a powerpoint is impossible. Any good experienced dev has plenty of their own side projects and they don't need your hype. If you want the fastest route, I recommend finding a contractor or dev shop to build the prototype at a fixed cost. I'm working with a developer in Romania and was recommended a dev shop in Ukraine. Don't spend too much on a prototype build. The prototype is a starting point not the end goal so use your resources wisely.
The main reason I probably won't attend FI is that I want to find advisers with backgrounds relevant to my project (Salesforce). I have very specific needs and don't think FI will help. I don't need motivation / structure. I already have a route to seed investment. Overall, I don't see what FI will give me except a $1k cost.
Hope this helps. Good luck.
