The mark on the base is a Qinq dynasty (1644-1911), Kangxi (1662-1722) reign mark written in kaishu script. You can find more information about markings at Gotheborg.com.
I'm sorry I can't help with the calligraphy. The only character I recognize is the 请, which is representative of the Qing Dynasty.
Hopefully one of the seasoned forum members will can give you an opinion on authenticity. I'm very new to this.
Good luck to you,
