I need more than 80,000 titles categoriesed logically

We currently have a list of articles that we have written for our website. There are over 80,000 titles currently on the system.

We would like to break these down into categories with 100 - 500 titles per category.

We have no idea how long this will take, but hopefully three days / 24 hours will be enough.

No extensive knowledge of the industry is required. We are a law firm specialising in personal injury, so we need you to come up with logical category titles such as 'claiming compensation', 'lawyers', 'car accident' etc. I can help you out with some ideas, but essentially need you to take control and look at the list, then come up with categories of your own.

Self starter needed, we don't have time to hold your hand.

Hope to complete the project by the end of the month.

Thanks,
