Need someone to take group of keywords and put related keywords into separate groups

I have a list of about 11,000 keywords in an excel spreadsheet. All are somewhat related to the search engine optimization field. I need someone to take these 11,000 keywords and organize them into smaller groups of 5-20 keywords each. Each group should revolve around 1 main keyword, so that I can write up an add that revolves around the "theme" of each group. For example, if one of the group's theme is "seo software", I would go through the list of keywords and find all keywords that contain the keywords "seo software" and place those into it's own group. I'll then move on to the next group and do the same thing. The goal is to have a bunch of tightly nit groups that revolve around 1 major keyword or theme. If you can do this, I plan to hire you for many more projects in the future. Looking forward to hearing from you. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
