Regarding all other questions you may ask - I suppose they all are related to your project and to your own wishes only and not related to our software in general, but whatever I could answer immediately: everything is possible

Our software comes free and it's open source, but that doesn't somebody should supply free solutions for you, or even search the web for you. Do it yourself or hire professionals.
