Hello Fr

If you are looking for a place that has a lot of PLR and MRR content, you can try out plrwholesaler.com
The free membership provides so much of PLR content that you will get tired downloading it. You can also upgrade...and you will get even more content.

You can also try PLRPro.com, Nicheology, Nichesinabox, ArticleUnderground, Infogoround

Hope that helps!
