There are good monitors, but they don't come with a sub. There's not a good combo for that price.
Your best bet is some 5'' monitors, they'll have enough bass you won't need a subwoofer. I use these at the shop - http://www.fullcompass.com/product/238886.html?utm_source=googleps&utm_medium=shopping&utm_campaign=googleps&gclid=CjwKEAiAj-KiBRC48YzhnLSg0D0SJAClOhK3yja4_LII_ZGVB9KQsK2pl6GNxHJv2tEA55H0S3L2aRoClX3w_wcB
They have more than enough bass.
