Dear Sir,
I have read everything and according to my technical team lead understanding, you required the free messaging Apps for iOS, Android mobiles and tab devices. The features you required are similar to WhatsApp and IMO including Audio,Video calls, live broadcasting and other features of walkie talkie etc. For Audio,Video, Live broadcasting requires the VOIP(Voice Over IP) and for that you have required to purchase the VOIP server.
Sir, there are lot of features required for the Apps and initial ballpark estimate is given below:
- iOS App: US $5,500 (Excluding Freelancer Fee)
- Android App: US $5,500 (Excluding Freelancer Fee)
- APIs + Backend and VOIP configuration: US $3,500 (Excluding Freelancer Fee)
However, I am flexible in prices, as my focus is not only on price but working with you to establish a good long-term business relationship is more important for me. Secondly, my team already understood requirements, so just because of the price difference, I don't want to miss the opportunity to work with you.
In terms of timeline, it may take 80-90 working days depending on the number of revisions and response time from your side, I am adding few days margin just for the safe side but if there are no delays from your side or not much revisions, then surely we can deliver it earlier than the given time-line.
Look forward to hearing from you.
Regards,
YK
