Thank you for the photos.
My research indicates that your Rosenthal Bavaria Elite set has a retail vintage store value of $1950-2100 assuming fabulous condition.
As for where to sell.....If you want to sell quickly at wholesale prices, try one of these sites.
I do not know where you live so I will make suggestions for three countries.
If you would like to sell closer to retail , some ideas are:
The internet has you largest audience of buyers. Place small ads on these sites or set up your own small store on these sites.
Etsy.com - no or small fees
Goantiques.com - more upscale fee based
Rubylane.com - more upscale fee based
Amazon Marketplace: http://services.amazon.com/content/sell-on-amazon.htm/ref=footer_soa?ld=AZFSSOA
A private seller to a dealer can expect 40-60% of retail value.
I hope I have helped you.
