Look no further!
I do mean it. I am a freelance writer who has been working at a company's administrative office for the past 6 years. Probably because I am a quite fast typist, most of my work at the office revolves around either typing / retyping contacts, announcements, etc in Microsoft Word, or, a lot more often, creating, filling out, merging, updating, and improving hundreds of Excel spreadsheets.
So basically, your project is literally in my line of work! I can say, with quite of certainty, that I wouldn't need more than 3-4 days to finish a project like this. However, I'm only saying this based on databases I've worked with - I wouldn't like to give you an exact "delivered in X days " time without at least having some idea of how "huge" this database is.
That said, I assure you, I respect agreed upon time frames. I'm great at meeting deadlines p and following guidelines. I'm reliable, and a big perfectionist - I can guarantee 0 mistakes, big or small.
Also, I'd be happy to do a trial task, and am also flexible when it comes to the price.
