Grading + window wells - what is the right cost?

Had a waterproofing company give me a quote for the above jobs. The house is old, so no weeping tiles, I suspect.

The work being done is on two sides of the house (north and south). Each side has 2 windows. One side is covered in dirt, the other is an asphalt driveway.

The proposed plan is to excavate down to the footings (about 5ft down and 30ft length wise on each side), install some weeping tiles that get connected to a sump pump, layer of aquaseal, yellow jacket, aquaseal, install drainage board, bring in weeping tiles to sump pump (around 16ft from one side and 3-4ft from the other side), cover with clear stone, backfill and tamper down soil, clean up. This does *NOT* include redoing the small portion of the driveway with asphalt (another few hundred bucks, let's say).

Total cost: $11,000.

Does that sound fair? I was thinking mid-thousands would be the highest quote I would receive, so either I'm clearly off or the quote is expensive (the guy seemed like a very decent chap though).

Thanks
