While not a toxicologist, I have some familiarity with various herbicides as a result of a background in environmental science, and I'd love to work with you to help you determine what long-term effects you may be at risk of suffering in the future as a result of your exposure to those chemicals.
My bid is for the first five hours of research and writing at my standard rate of $30/hour. If that doesn't cover what you need, we can reexamine at that point, and before I start logging billable time, I'll work with you to ensure that I know exactly what you're looking for from me.
As previous clients can attest, I pride myself on my communication with you to ensure that you get exactly what you're looking for, and I'd love to work with you on this project.
Please don't hesitate to reach out with questions or to discuss this further. Thanks!
