Dashboard - Google Data Studio

I am looking for some to build out a dashboard for me in google data studio, using data from Amazon seller central and Amazon advertising. I have reporting templates in place (i.e. currently manipulating data in Excel and transferring data into powerpoint) so this would just need these to be mirrored in GDS. Initially we would just use GSD by upload CSVs, but would eventually like to add in a connector. Once the dashboard has been built we would like someone to run us through the basics and help with any troubleshooting in GSD and also offer help and advice of google big query and next steps of a connector.
