Landscapers & general contractors probalbly won't have the back ground
to solve your problem.
A civil engineer or landscape architect would be trained to solve these
problems.
However, as Norminn suggests, you may be able to solve the problem
yourself.

The land surface should slope away from the house on all sides.
Your house floor should be six inches or more above grade on all sides.
If you can't manage that, contour the land to direct water around your
house.
A berm or wall should do it. Make sure the water isn't trapped.
