[PAID TEST] Find personal emails and mobile numbers for US licensed professionals

I have a list of licensed professionals in the US, taken from public state license records. For each person I need a personal email address and a mobile phone number, plus any public social media profiles.

I will start with a paid test of 50 records. If the results are good, I will send up to 20,000 records in batches.

What I send you (after the project is awarded):
A CSV with: record ID, full name, state, license type and license number, plus city, employer and LinkedIn profile where I have them.

What I need back (one row per record)
- Record ID, unchanged
- Personal email (up to 2)
- Mobile phone (up to 2), marked mobile or landline
- Facebook, Instagram, X and LinkedIn profile links, if found
- The source of each email and phone number
- A confidence level for each record (high, medium or low) and how you confirmed it is the right person
- Leave a field blank if you cannot find it. Please do not guess or build emails from name patterns.

How I will judge the test:
I will check your results against records we can verify, test every email and phone number, and look at how many records you found. A wrong person counts against you more than a blank.

Please answer these questions in your reply:
1. Which sources and tools would you use to find personal emails and mobile numbers?
2. Many people on the list have common names. How do you confirm you have the right person, for example when two people with the same name live in the same state?
3. What do you do when an email bounces or a phone number is wrong or disconnected? Do you replace it at no extra cost, and how quickly?
4. What is your price per 1,000 records at volume (up to 20,000)? Do you charge for every record or only for records you find?
5. How long would the 50-record test take, and a batch of 1,000?
6. Have you found contact details for individuals before (rather than business contacts)? Tell me briefly what the project was.

Start your reply with the words "Verified 50" so I know you have read the full brief. Replies that do not answer the questions will not be considered.
