Waterproofing basement/Foundation repair?

We have a 100+ yr old house that we have remodeled. The foundation is brick and the mortar is in terrible shape. The basement leaks, not terrible, but enough that there is water around the edges after it rains. Tuckpointing seems like an impossible job. What would it cost to have the basement waterproofed by a professional? Any ideas that I could do at home on a small budget?
