Believe it or not "looking for a developer" is not the first thing you should be doing after you have have solidified your idea and are ready to start building your product! Here's a step by step guide to what you should do:
1. BUILD MOCKUPS FOR YOUR PRODUCT
Software should always be documented before starting development. Because you are building a startup product and not a complex banking software worth millions of dollars, you will not write thousands of pages of analysis documents but still you should have someting written that specifies the scope of your small software project. For startups, mockups are the best. Mockups are basically the screens of your app with arrows, decision boxes and notes to specify functionality. Remember that mockups do not have any visual or aesthetic value, they do not have to look nice but they should contain every details of your product's functionality, flow and navigation. Mockups do not represent your app's visual design but they will be an important input for your visual design process along with many other crucial project documents including but not limited to your wbs and project plan!
