Excel Macro (Written in VBA) to Evaluate Simple Case of Dijkstra's Algorithm Needed

Hi there --

I'm currently looking for a programmer to do a short little job for me.

Here's the thing.

It needs to be in excel and run off a macro (VBA)

There is a mine of width W (user inputs width into the screen).

Each unit of conveyer belt is 7 feet long. So W/7 = Number of Nodes.
The conveyer belt goes in a straight line.

Each node has a cost associated with it. Also input by the user (Need to have the exact number of fields "light up" or something so the user knows if he's entered too many/too few costs when entering them.)

OUTPUT:
The Combination of Nodes that lead to the least cost produced.

For example: a Sample input could be:
W=35

Cost Node 1 to 2: $500
Cost Node 1 to 3: $600
Cost Node 1 to 4: $200
Cost Node 1 to 5: $1000
Cost Node 2 to 3: $200
Cost Node 2 to 4: $400
Cost Node 2 to 5: $1000
Cost Node 3 to 4: $100
Cost Node 3 to 5: $400
Cost Node 4 to 5: $25

Again, the program needs to:
1) insure that only one unit is coming in and leaving during the analysis (minimum cost requirement)
2) Output the node combination that has the minimum cost (ex. 1 to 4 to 5)
3) Be pretty user friendly

This is a pretty easy program/algorithm to code, I've done it in C++ but don't have the time to do it in VBA ... pay is negotiable and will pay after completion/evaluation through paypal. email me at rmullen@mines.edu if you are interested!

Thanks in advance.
