Outside Basement Waterproofing

Does anyone have a “guess”-timate on the cost of waterproofing your basement?

I have a nice basement but should there be a very heavy rain and by heavy I mean like the one we just had this weekend, I will get water leaking in from the wall (and only at the base) that particular wall is where I have soil and grass behind it outside. When the rains are torrential and that soil fills with water it will begin to leak into the basement only in that specific area. No damage but a mess just the same. Does anyone know the cost of waterproofing? Someone suggested B-Dry. Before I contact them I just wanted to get a feel for costs. Thanks for any information you can provide.

3,000 and up depending on the size of the basement. and area needing treatment.
