Basement Flooding in KCK, help?

[Jacob Compton]

Hello everyone. I have a property in Kansas City, KS which has been receiving a lot of rain and has a basement that has flooded. I am looking for some good contractors to help me diagnose and fix the issue... I had some water standing around the home so I have done some grading myself and extended my downspouts but I had water coming in in multiple corners of my basement which suggests to me a possible foundation issue.. Installing a drainage system is likely to cost me 10-15k and I have already been quoted 10k just to clean the basement. The basement is about 1000sqft. Can anyone recommend a good contractor for this area or any other advice for how I may keep the water out without spending 20k+ in fixes? Or am I just screwed?
