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 (MS-DOS based desktop software), into Web-apps since 2001, asterisk based VoIP solutions (asterisk, freepbx, freeswitch, elastix) and Wowza/FMS based video streaming/VOD apps for about 5 years. We also maintain our clients' servers (mostly linux) on their behalf besides fiddling with our own Linux test bed VPS's and VMs. Currently exploring International clients for video streaming, backend support and VoIP related work through these portals for mutually beneficial and long lasting collaborations.
You're asking for too much in too little money. Well, not too little but not sufficient enough. If someone has it done already, they will be able to give in your budget. We can do the needful but it needs dedicated time and I anticipate it to be around $1500-$2000, which includes everything you have mentioned. Let me know if your budget allows for that.
Please feel free to ask any questions you may have.
Best of luck!
Sincerely,
Inderjeet
