These people leveled your yard, and now it pools with water? Is that accurate? If so, those hardscapers fucked up bad. They shouldn't have been aiming for level; they should have been grading it away from your house at 2%. How old is the home? I have pretty good experience with french drains, grading, and water intrusion investigation. DM me and we can have a phone call to go over options.
Be aware: someone in your position is seen as a cash cow for basement dewatering systems and foundation repair. Dont trust any of these people if they haven't spent an hour looking at your house during a big rain. Only you have the capacity to get to root cause.
