Database entry /database cleaning / company research

General information for the business: We make short videos that promote charitable and environmental issues
Description of excel work: We have a database of company names and we need contact details of the communications / marketing person that works within those companies. This will include, full names, correct personal emails, mailing address, sector and job title.

We are looking for someone who has great attention to detail because this is something that is either right or wrong. For example we will not accept info@ or contact@ emails.

Attached is a file that explains in greater detail what we are looking for.

I have tried a few people and been a bit disappointed with the results so I would start you off on 100 contacts and then if that goes well there are up to 1000 to do should you be willing. Let me know how much you would charge for both these pieces of work. ASAP please!

Hope to hear from you soon.
