To do the job right you will need to seal the concrete from the outside and then on the inside. As well, adding drainage on the outside is a must. We added drainage along the footing and then added surface drainage to get the water away from the house. Definitely a good sized project. Get references from anyone that you are considering hiring. Generally speaking this project would take a 2 man crew probalably 4 to 5 days to complete. Good Luck and keep us informed as to what you do and how it works.
