[Selling Gacha Items in world?]

So I have plenty of gacha items that I wish to sell. However, I don't want to make a marketplace in order to do so. Is there a place to sell some of it in world? If so, where? 

 

Thank you,

[What is the easiest way to earn lindens without having to purchase them?]

I've been on SL for quite some time now, and I never really bothered with buying lindens; nor do I plan on buying them. I normally got things from groups and such and at times, some cheap things here and there on the Marketplace. However, I would like to find a quick and/or easy way to earn lindens. I'm also terrible with creating things in secondlife, for normally I only ever chat with people. I would be exraordinarily happy with being able to find a good way to earn.
If somebody could please answer my question, that would be amazing and greatly appreciated!

Thank you very much,
Mickey.
