Invision Prototype

I need help to build a working INVISION file that correctly links all of the views/buttons in our Application(s). There are aprox 50 screen views of the entire flow which is split in 2 apps (as it is a marketplace app). The views already exist, it's just a question of connecting them into a prototype and delivering the source/demo file. This will be used for sales presentation so it needs to be very professional and validated. Since Images are in Spanish we will privilege Spanish speakers. You might need to add some sort of "simulation" to the presentation to fill in for keyboard entries, transition and 3rd party widgets but it is a very straight forward project which needs to be completed over the weekend.
