The artist is Nicola Simbari. Price depends on what type of artwork it is with prints (and by prints I mean original,signed, limited edition prints like lithos and serigraphs, not mass reprinted repros) bringing less that original paintings but still selling for some decent money. A quick search brings up tons of info. It is a very nice picture.
***Just a quick tip for anyone trying to research artwork - I took your image, cropped it to just the artwork then dropped the image file into Google image search box (click on image option top right of Google page). It will search for visually similar images. Usually it will just bring up a bunch of pictures that look like it in composition, subject and color (results can be hilarious and unexpected sometimes) but sometimes with an artist who has a distinctive style or a with an artwork that has been on posted somewhere on the internet before it will find the exact image or a body of the artist's work. The result with your piece was immediate - gave me the name as top suggestion and brought up tons of his work.***
