Required Microsoft Excel freelancer for Excel S-curve job

I need a model which calculates interest during construction over a period of time, using a cumulative normal distribution. Interest rate is annual, calculated monthly.

Inputs:

• Number of months (build duration)
  
• Interest rate
  
• Different distributions, front load, back load and normal

Output:

• graph
  
• Amount of interest paid
  
• Amount of interest paid as a % of total build
  
• Calculates based on a macro button to prevent circularity once inserted into a larger model

This is a good project, I wish I had the time to build it. I need a quick turnaround too.

Negotiable price. Feel free to suggest additional features.
