Need window well and basement windows replaced. Recommendation?

I live in Newmarket. The window wells in the house have bent and have come free from the wall letting water in. One window frame looks rusted right through to the point of water coming in through the frame. I need to get them both replaced. Two window wells and two small standard size basement windows.

Can anyone recommend a decent company? If anyone has had any experience, can you give me a rough estimate on what this may cost?

Thanks so much.
