Comprehensive Business Data Curation and Mapping

I have about 5000 business names with about 100 columns of other data for each in 12 CSV files (much of the information I do have is unimportant but I can delete the columns I don't need- the information might be handy to find the things I do need)... (Budget: $30 - $250 USD, Jobs: Data Analysis, Data Cleansing, Data Entry, Data Management, Data Processing, Data Scraping, Excel, Google Sheets, Web Scraping, Web Search)
