Looking for any referrals for individuals or companies. Need something super reliable, to network around 10-15 computers. Want to be able to work directly from the server with Image files. Thanks!

I can recommend an extremely reliable company, but based in Bangkok. Call it a backup solution if you can't find anyone local.

I don`t know whether you have a wireless router or ethernet.

But setting up networks between ethernet connected computers is very easy.

You only need to buy a D-Link plug and play connection appliance as pictured below:

I think "seesip" is asking for something more than just a hook up of cables.

From the question it sounds "seesip" wants a solution where files are stored server side and can be worked on by any number of people on the network based on a user access system.

It would be critical that when one user is selecting to work on an image others should be locked out of accessing the image with a prompt stating that <user x> is currently accessing/modifying the image.

Although computers are generally reliable when used properly, it is well known that users generally do not follow recommended usage guidelines. This is why securing critical data should be top priority. It sounds that the image files are critical to seesip's business and would require at least a redundancy solution (eg. mirroring of files real time with manual backups to non volatile media frequently). It is not a matter if something would go wrong, it's just a matter of when.
