I haven't heard of any Tableau consulting firms in the area, but connecting to data is really quite easy with Tableau.
There is a native Google Analytics connection in Tableau Desktop. Are you having trouble just connecting to your data? Or, are you needing help with understanding the data available in Google Analytics?
Regarding Simpleview... there is not a native connection for this, you may need to work with simpleview to see if they can provide you access to your data via export or ODBC.
I know some one that may be able to help you.
Please give me a call to discuss.
