3D model in app

I need to develop an application which includes 3D models of some objects (not to be disclosed), along with text content. The 3D models will be made either by the dev/team I outsource this project to, if possible, ELSE, it can be outsourced to some 3D architect/modeller and so the developer will only need to integrate the 3D models into the simple application. So, the app will have an .ipa & app data to be downloaded (which will be in 100 to 200 mb range). If its possible, plz bid for my proj asap, else plz tell me clearly if its not possible or easy on iOS.
