Re-thinking my office: computers, dealers, server, communication and services?

My office has to be renewed: 4 floors, 5 rooms per floor, about 40 computers, 40 printers and one Win server used for back-up.
I'd like to re-think everything so to make it more efficient, maybe renting computers and printers, reducing printes number using net-printers, reducing faxes using fax-servers and so on.
Do you have any idea what is the perfect way to implement everything?
About the server and services for my co-workers, I read something about "productive" environment...I would like to use the server so to have an address agenda shared between people (having access control over some of them), shared documents and so on. Do you know what kind of server software and service are used so to implement a MODERN way of working?
Finally...some workers are around the country for long...how is possible to let them have documents, agenda and information stored in the server...in a safe way?

Any other suggestion about something to implement that I forgot?

Thank you.

You are asking for a several thousand dollar (US) consulting job.
I would suggest contacting Microsoft for the name of a local partner who can meet your needs - everything you mention is what I do every day.

If you are in the US, you can go to http://www.microsoft.com/smallbusiness/p... and search for a local IT specialist.

If you are not in the US, try the microsoft website for your country.

You could talk to the IBM company.They will have things like service contracts.Think most modern.A wireless system might even cut costs.

For your fax situation, you should try an internet fax service.
You get your own fax number and you can send/receive faxes using your email. You can create a contract with a provider if their plan does not suit your company's needs. Also, it takes less than an hour to set for your entire company.
