Hello,
I am Certified in Tableau 10, and have 4+ years experience working with many different versions of Tableau I also have 6+ years experience with business intelligence, Oracle, SQL, & Hadoop. I have transformed dozens of Excel reports into Tableau dashboards.
I look forward to talking with you and seeing what you need done, what your expectations and what you are feel like you are missing seeing in your data without a dashboard. I believe trending, forecasting, and some comparison charts will be a great start. I can also focus on a great user experience with it so there wouldn't be an confusion or misunderstandings when looking at it.
I know I don't have any "experience" on freelancer, but I am trying to build that up with what my expertise is and hope you will give me an opportunity to do so. I can promise I am one of the better developers on here with Tableau. If you also wish, I will do a prototype of your data if you are willing to send it to me.
All the best,
Scott Dickinson
