I'm working on a project for my network design class, the project is to create a LAN for a business that has 4 locations in a town. I have Visio at my disposal for the network diagram but I am having a bit of trouble actually creating the whole shebang.

note, I am going to school for IT yet 80% of my classes have all been theory, not a darn thing on actual network set up and design. Which is this class, the TA is completely useless when it comes to this type of stuff and the prof just had a 2nd heart attack so he's in and out of his office. which is why I have come here.

Now the business is fictitious and its what ever you want it to be, main idea is I am making a network for these 4 locations.

The business description is as follows

So, as far as a network for one of the shop locations I have the following


(haven't made the notations for wireless yet or anything much. The red lines are Ethernet)

I haven't gotten around to getting the specific hardware yet, just trying to figure this all out. I still need to figure out how to get an IP assigned for the company, the costs associated with that as well.

The overall specs for the assignment are
So, what do you think? I still have the other location to figure out as well as the centralized file, mail, web servers to figure out too. Budget is set at $50k

feel free to PM me if you feel like helping. thanks guys
