Finding a Job that does't require skill is going to be tough to find. (Depending on what you mean by skill)
Every job in Secondlife Requies Skill and a knowledge of Second Life itself, the viewer you are on, and how to Emote. Second Life is treated literally like a Second World, so just like Real life you need skill to get a job. Most people when your applying for A Photographer or say a Designer, or even a Model they are going to want you often times have that skill from Real Life and or a General Knowledge of that particular Skill.
The easiest jobs to get Are in Clubs. Clubs are found all over SecondLife as they are a great place to hang out, dance, have a few drinks, rent an Escort or even watch Dancers+ More. The normal positions in a Club setting are =Host, Dj, Dancer, Escort, Bartender, Manager, Secruity and Sometimes Greeter= All of these positions Require some form of Skill.
A Host you need to know how to write Notices, how to Emote, How to work Event Boards
A Bartender you need to know how to Emote as well, and knowing how to mix the drinks in Real life is often helpful and makes for a Better RP
Dj you need to have the skills of knowing your computer, knowing what Dj software you need and a General knowledge of SecondLife as well
Dancers and Escort you need to know how to Emote extremely well. You are basically getting paid for emoting and your sexual Appeal. Not only that, if you are an escort you need to invest some money into naughty Part for your avatar.
Being Security you need to be trusted. You have all the power to kick and Ban whomever you want when you want; and you have to be mature about the situations at hand and not just kick someone because you dislike them.
From my experience being in SecondLife for over a year now. I do know that most clubs want you to be at LEAST 30 days old (meaning you have speant a Month in SecondLife getting to know the Virtual World and learning how to work your Viewer) There are some that don't require and Age Limit as far as your SecondLife age, but there are Very few who do.
