I will convert your idea to a reality and get it listed on Apps.com where ~600,000K users visit daily. How much? I will give you a fixed bid price and I promise to not go over by a single penny. No excuses or hourly rates where you end up taking all the risks.
Pretty darn fast. Of course, this is going to depend on many factors, which we'll discuss. But considering that I'm an expert in QuickBooks Integration and have successfully launched on Apps.com I will beat an agency or solo-consultancy that hasn't been in the "trenches".
Being a business owner myself who has launched products I can consult your business in many areas like marketing, competitors, and build cost. My desire is to partner with you to make your app a financial success. We will focus on getting an MVP out the door, on budget, to test the market.
