Time Series Analysis in R or Python

Hello,
READ THIS BEFORE BIDDING.

I have some data that need to be analyzed and get some insights into the data. This is a rather well structured data of sales orders (time series). I would like to analyze this in Python or R and then perform some visualization in Tableau (preferably in R). The ideal person will have a reasonable knowledge of time series analysis in R or Python (R preferred). If you have good skills in Tableau, that will be a plus but this is not a must.

To summarize the person should have one of the following

1) Time Series Analysis and Forecasting in R and Tableau will be great (Ggplot2 is fine)
OR,
2) Time Series Analysis and Forecasting in Python and Tableau will be great (Ggplot2 is fine)
OR,
3) Time Series Analysis and Forecasting in R or Python with no Tableau

This is not a project that I can just hand off to you. You will have to work with me for the next few days on and off. Therefore, good communication skills are necessary. Please be frank and tell me what skills you have instead of saying that you know everything.

Thanks,
Partha
