Startup Idea : Trades people app

I find it that getting a trades person to come and quote a job around the house is usually a big process. Imagine if you had an app that could simplify that process. For an example if you needed a painter and within the app you could take a photo of your house and what needs to be painted with some basic questions and this information would be sent directly to the trades person. The trades person could review and quite in a very short time the price could be eg: between $3000-3500. Once the user gets this information back and they know roughly what the cost is they could then request a formal quote from the tradesmen. This would eliminate time wasting for both the person wanting the quote and the tradesman. I belive this could work for any trades job. Please feel free to message me if you like the idea so we can discuss it more.
