Hi, You'll find many packages offered by Local Himachali service providers and some popular names like Make My trip, Thrillophilia. These packages will start from ~7000/person and can go as high as you need. An interesting trip I came across was the recent Manali package from Tripoto, I recently went for the Mindful retreat and loved it, so maybe give this a try. Here is the link: https://www.tripoto.com/collections/tour-packages/celebrate-a-white-christmas-in-a-winter-wonderland-163940353239
Hope it helps!
