I need an app developed. The app will be very similar to Poshmark, the independent marketplace app. I pretty much want to follow the same format. I'm looking for someone who is very good at developing applications for both formats. We can agree on an initial price, but I'm also looking for a partner that can help update/add sections ect., for an additional fee whenever it need be. All of this can be cleared up in a contract that we both sign so It works out for both of us. Preferred if you were from the USA, please send me a message of your work and please do not bid if you do not know what type of application I am talking about.
