I need someone to check a list of addresses against a database

i have got a list of addresses.

these addresses have used a online tool we provide (there Is 1265 addresses in total)

I have 1 website, which can provide us the 2 dates we need for each address.

i need 1 date of when the property last sold
the 2nd date is the date it was last marketed.

i need these put into a spreadsheet so I can track which properties I will to look into more.

this needs to be done ASAP.

please comment with the word surrounding, so I know you have read the spec. thank you!
