it sounds like you're interested in purchasing a small business server, but for what you're requesting, a windows XP pro machine configured for file sharing would work fine. save your money for the server until a later time.
the 317 area code is Indianapolis? I don't know of any local company, but you might try Geek Squad. Keep in mind that they'll try very hard to sell you a machine (I think they peddle HP servers with windows 2k3 SBS) that is overkill at this juncture. SBS server or not, what you specifically need to ask for is how to setup file and printer sharing and read only access to these files. also you need to install adobe acrobat on your server and share the acrobat distiller printer. that should take care of all your issues except the publication management software. for that, you'll need to simply check the system requirements and match it to the machine you're buying. Keep in mind that you may have compatibility issues if your software is to run on XP or server2k3 and your machine is running Vista.
the solution provided should run you about $1500, ($3000 if you go for a SBS server)
On a final note, if you can find a smaller company than geek squad; use them.
