should I outsource article re-writing?

I'm posting this here, since I'm asking for advice, not for actual article writing services;

I will start my very first adsense website soon enough and I have already aquired enough PLR articles to last me a long while!
The only problem is that, as we all know, PLR should not be trusted! so I decided to re-write all my articles before posting them ... now the question is: are my time, or my funds more limited??

This being my first real project, I don't have a whole lot of money to invest, so I started out with 500$; I paid 20 of that for my domain name, so that leaves me 480 for everything else; I must say that this is a fairly large project, as I found quite a lot of long tail keywords that come together under the same "umbrella" keyword that I'm going to use;
For all this, I have between 500 and 1000 PLR articles ready to go!

what do you think, guys? I would basically pay a 5$ gig on fiverr for each article ... do you think it's worth it? as I don't know adsense so well, I have no idea how fast I could cover my expenses; maybe someone more experienced could advise me on a course of action? thanks in advance!

i only outsource if i dont have the time. yeah $5 for a rewritten article is overpriced

I went over to freelancer and I like the prices for rewriting articles they have there!

I, too, outsource it because of the lack of time! I really need to get a lot of things done and I can't afford to take care of this, too!

what is the price I could expect to pay for a quality, SE and keyword optimized rewritten article?
