Hi:
I'm very much interested and able to work on your project. I've setup and maintained many Linux based servers for personal and business purposes and though I normally setup the hardware, and maintain it myself, installing your control panel of choice is simple for someone with my experience. The only caveat to this is if you're choosing hardware-based controls (like controlling a RAID server), since I wouldn't have access to the hardware.
For this project I'm assuming you will provide the software yourselves, since that would be an extra, often monthly, expense. Choosing the control software depends largely on your needs, but from what you mention, it seems several programs might be needed to encompass all you want.
If you give me more information as to your specific needs, I can help you decide on the better program within your budget, even before you decide to award me the project. No strings attached.
Lastly, if you need long term services or maintenance, I can provide you that service as well (hourly or on retainer as needed), though we can discuss that at a later time. It is often better if the person to maintain/fix/upgrade a system is the one setting it up, since it saves you quite a bit of time and money. I'm based in Florida, Eastern Time, so we most likely have similar hours of operation, and you'd be able to contact me directly, not at midnight, on the other side of the world.
Feel free to contact me with any questions, doubts or requests.
