Hi,
Thank you for posting your requirement. Please read further only if you can allow this to be done in 3-4 days.
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.
Which OS is plesk on, Windows or Linux? Considering the "tediousness", each sites need double the data transfer as against doing server to server, and there could be issues such as file case-sensitive filenames or folders. Therefore, it will take time. We have an 8Mbps connection still anticipate this to be done in 3-4 days (adding each FTP account etc, then mysql, we still don't know the volume, if there is 2GB of mySQL, it will take longer). The bid amount is also proposed accordingly. I think you'll be able to understand.
If you have any questions, please feel free to ask. Please feel free to ask any questions you may have. We look forward to hearing from you and building a long lasting and mutually fruitful relationship.
Sincerely,
Inderjeet
