I need an app similar to whatsapp. I need Android as well as iPhone. We need a team who have already built the app before and can do show a demo on iPhone as well as provide apk files for Android with custom modifications as a proof of originality of work (like a logo of client's company or something similar). We are not looking to develop this app from scratch.
Please provide individual quotations for each platform (iOS and Android) as well as combined quotations for both platforms.
This project is from a trusted client. And a long term partnership could be well expected from a genuinely capable team.
Whoever quotes $3000 or less for combined bundle will be hired immediately.
