I basically only do editing jobs and the occasional writing job if it looks interesting. I guess I should selfishly say "Yes, stay away from editing jobs" but I won't.
There are good jobs to be found but it can take awhile. I will do small samples at times but I never edit the whole document. I typically do two pages at most.
I like doing this because it also gives me an indication of the client's writing ability and how much work is involved in editing--particularly if it's a fixed-price job.
Unfortunately, there are also a lot of low-ball clients here and freelancers who are willing to work for those prices Of course this is probably because a number of freelancers feel they can edit simply because they can read. I'm not directing this at you, but it is a fact with some of the profiles I've seen.
