Update already created MS access DB

I hired a freelancer to create an MS access DB. Now I want to update a few things on that. But that freelancer is not available currently so I am looking for someone who can update or add few things on already created MS access DB. I can provide complete details of what I want to update and the current DB file also. 

Only bid if you are a serious freelancer.
