It's okay - in fact, we're glad to hear you're doing the last volume as well! Better stick to the series till its very end, don't you think?
We won't mind you taking the time you need, I'm sure there are lots of people on this forum who have lives to live as well. Good things await those who wait, isn't that correct? And quality scans - both in terms of translation and editing work - of Get Backers surely is one of those good things well worth wating for!
Good luck, both of you!
Be cheering you~
