Dear business people, an iOS app actually takes a lot of work
As a "business person" I need to know three things to hire someone:1) how much did it cost other people to build similar apps (comparative analysis)   
2) that you are able to build the product successfully (reducing technical risk)
3) that the price is low enough that the estimated Rev will produce a return (ROI)-
If you can present those points clearly you will be in a much better position to make more money with less frustration
