Monte Carlo simulation in R

I am looking for a skilled freelancer to assist me with a Monte Carlo simulation in R. The simulation focuses on the net present value and internal rate of return of a startup business. I have the specific data and inputs for the simulation, but am open to suggestions when it comes to stochastic variables. I need the freelancer to perform Monte Carlo simulations with the first 60 months of operation. If the freelancer has expertise in other domains related to startups that could help inform the analysis, it is welcome. Knowledge of R and Monte Carlo simulations are prerequisites.
