Online research / Data Entry - 1900 occupations need industry sectors added in Excel

Industry: Technology
Data to include: Match industry sectors to occupations
Extra notes: This is a straight forward data entry job for someone who enjoys online internet research (simple use of search engines)

I have a list of 1900 occupations and I have a list of predefined industry sectors that need to be added to a separate excel column

I need someone to assign the relevant industry sector to each location. This means researching the occupation or job title and understanding which industry sector to correctly to assign. There are many niche occupations so it's essential the correct person is thorough with their research.

I also need a separate column where all the occupations are converted to plural where appropriate for example Doctor would be converted to Doctors or Shop Keeper would be converted to Shop Keepers. Many have already been done so it's a simple case of checking as you move down the sheet, and where appropriate convert those that haven't been converted.

The job will take approximately 7/8 hours for someone that has a good typing speed and is actively engaged in the project throughout the day.

See the attached example which shows the first few already done.
