I do about 1k a day, but that's only recently, because I have a new wip I'm crazy about. Sometimes I only wrote a paragraph, on better days I wrote a few pages, but if the paragraph was good I'd still feel better than after ten pages of crap.
My advice would be not to worry - take your time and find your own pace. There are people who write a first draft in two months and spend an year revising; there are others who write slowly and take an year for an already polished result. If you need something to motivate you, you can start small (500, but I know people who try for 250 and do well - if you're busy/a slow writer, anything can go as long as you write every day, or regularly). That way you won't get discouraged if you know you can't reach your goal on a specific day, and you can always write more than your goal anyway.
Another way to do it would be to write until the scene ends. That's why I don't like wordcount pledges: my goal may be about 1k, but if the scene is done and I feel like I'm done for the day, don't have the energy and time to get started on the next, I'll stop there even if the wordcount is terribly low. That doesn't mean one scene a day, it just means following the pace of the book. Or another well-known strategy is taking a time for writing - say, two or four hours a day - in which you sit at the keyboard and type or do nothing. No alternative. It depends on what kind of person you are.
Revision time depends a lot on whether you outline or not, whether your story changes on the way, on how solid a first draft you write and if you tend to write too wordy or the opposite.
Best of luck with it. We've probably scared and confused you big time, so join in the fun.
