If you are thinking about raising money, you must have a technical co-founder.

As suggested by Cooper, first thing I would do is figure out whether there is demand for the product you plan on building. A good way to get consumer feedback is via landing/lead pages. You can run a add on Facebook or any other social media for quick feedback.

Once you have data that shows demeand for your product, you should focus on getting a technical co-founder. I would highly recommend not to hire a freelancer or dev shop to build the first iteration (especially since you have no tech skills). Having an in-house expert and building the web app right from the beginning will save you from many headaches in the future. Focus all your energy on finding a technical co-founder, that will be the best use of your time at this point.
