stormwater runoff from neighbor

I'm looking for an experienced engineering professional to help me address an issue with stormwater runoff from my neighbor. Specifically, the issue is flooding, and the solution I'm looking for is an engineering solution. My budget for this project is between $1000 and $5000. I need someone who is able to assess the situation and create a plan of action that will enable me to properly manage the runoff. The ideal candidate will have experience with engineering solutions related to stormwater runoff and be able to provide recommendations on the most efficient and cost-effective way to address the issue. If this is something you're interested in, I would love to hear from you!
