Update industry categories on list of prospects

We have a list of 800 companies that we need to have the correct industry category specified. On the spreadsheet we have the company name, billing and shipping address, phone and website (if available). You will need to look up the company, see what they do and find the correct industry category for them. We will provide a list of industry categorizations that you can choose from. There are 113 categories to choose from that are in 21 industry parent groupings. I have attached a sample of 10 companies and on sheet two of the spreadsheet is the industry grouping list. If the URL is missing you will need to look up the company by the address or phone and if they have a website, please add the URL in to the spreadsheet. If you do well on these 800 we then have a lot more that also need to be updated.
