you can do a google search for ATV snowplows to get more info. The Cycle country plows and the heavier Warn plows are excellent and a little more affordable up front but remember if you order online, the shipping is going to be steep unless you find an online store that ships for free. If you have a reasonable Polaris dealer nearby you may won't to check out their prices on the Glacier II plow, they are a bit more $$$, but you won't be paying shipping costs that tend to even things up price mise and they are excellent plows made to fit your sportsman with the quick attachment feature!
For the winch, I have the Gorilla 2500# unit and I'm very happy with it...it may be just what you are looking for.
Hope this helps and welcome to the forums!
just checked www.rockymountainatv.com
they have the Tusk line of plows, (built by Cycle Country and rebranded as I understand), $340- $380 for the complete plow kit w/mount plate depending on plow width. All you need to add would be the winch
I may be wrong but I believe their shipping is free on $100 and above orders
