Hi,
Thank you for posting your requirement.
My name is Inderjeet and own a small 4 member IT services firm based at Chandigarh,India. We have been into IT since 1994 (desktop software), into Web-apps since 2001, Wowza/FMS based video streaming/VOD apps for about 3 years and Asterisk based VoIP solutions for about 2 years now. We also maintain our clients' servers (mostly linux) with these technologies, on their behalf, besides fiddling with our own Linux test bed VPS's and VMs for R&D and testng purposes. Currently exploring International clients through these portals for mutually beneficial and long lasting collaborations.
We have done similar works and can assure you this is not a $500 work. The basic setup alone is $500. Consider user and stream management on top of this. We can do this for $1000 if you can finalize within 2-3 days.
Let me know if you have any questions or concerns.
Sincerely
Inderjeet
