URGENT: Provide URL and dates for Real Estate shows listings

Hello Bidders, I have an incomplete list of real estate events around the world and now I urgently need to get the work completed. The work consists of filling out the dates and URL fields of the attached spreadsheet. The listing contains about 200 events and the dates are missing for 78. These need to be quickly researched and filled. The URLs are missing for 120 events. These also need to be researched and filled (if available). This is urgent and I would require the results in the next 12 hours. Please do not bid if you cannot complete it quickly. I do understand that not all info will be available but do your best in getting accurate information. Sam..
