As a bootstrapping start-up we are thinking of saving on the IT hardware cost by making more use of the hardware that we have.

As a solopreneur I have a laptop config : intel core2duo processor, 3Gb RAM and 250 GB RAM. Now we are planning to increase our team to 3 members. Will like your suggestions on the nest cost-effective step that I can take so that I can use the computing power of the existing laptop to act as a kind of server and then buy to more monitors where the new recruits can do the daily work on and they need to have different login id and access and they dont need access to all the files/applications as are available in my laptop. We use internet intensively to do our day to day activity.

Please share you experience, whether you think this is a good ploy or there is any other more effective way of achieving the same result.
