Hi,
I have a good experience in Database Administration and Database Development, etc... But I'm a new freelancer so I doesn't have lot of reviews in these relevant skills. But I confirm you I can create an ERD diagram with all requirements (crow's feet ERD notation, Attributes and PK & FK) very well. I can create the diagram in Visio and copy paste into word file. Also if you want to negotiate budget and days I agree with it.
Regards,
Zajjith
