Waterproofing: we just got an estimate for our basement. What's best for us, and is this a good estimate?

We've had water problems in our basement since we moved in (this past February). There is a makeshift French drain that runs through the basement and gets clogged with mud, so water doesn't make it to our sump pump well. There is a crack in the foundation by the furnace, and water comes in from there. We have a 167 linear foot house, which is how they calculate price apparently. It's usually very damp down there and we have 2 dehumidifiers going at all time. It is a fieldstone foundation, and the house is over 100 years old.
The gutters are in good shape. The downspouts are old but aren't dribbling water on the ground. There is no plant life near the house and concrete angled away on all sides. We are at higher altitude than normal and not in risk of flooding. We've noticed that the water problems are worse after sudden, heavy rains.
We had a waterproof company representative come out today to give us an estimate, which ended up being around $25,000. This included a lifetime warranty free of any water problems. The estimate included: digging around the house perimeter to below the frost line, repairing exterior cracks, then applying waterproofing and a plastic barrier to the excavated foundation, placing exterior drainage pipe and gravel to cover it, placing an interior drainage system under the basement floor around the house perimeter, repairing interior cracks and sealing the walls with a custom plastic, adding two sump pumps with backups, and a dehumidifier/air filtration system.
The company (EverDry) has been around for about 30 years and are pretty established in the area. Is this a reasonable price for what we are receiving? I know nothing of home structure and waterproofing. What were your experiences? What should we look out for?
