Project "Middle" - Research Manager and house number, fill lists

Good afternoon,

I need someone to research and add the following information to two Excel lists:
- Current managing director of the company with first name, last name, salutation and title
- Addition of the house number (street name is already available)
- Checking the companies/addresses for correctness
(See yellow markings in the attached example list)

I have to lists: 1. list with about 500 addresses 2. list with about 1500 addresses

The lists are needed by the beginning of next week at the latest. It is required for the creation of a form letter.

Thank you for an offer including an estimate of how long it will take to create it.
