Would a Milk bar be a successful marketing idea/ project?

As a final project in my marketing course, we're suppose to create an original good/service and work with it and plan a presentation filled with reasons why it would work, targets, forecasts etc etc.
Another idea is a student utility app, where it can be downloaded into an iphone/ etc and as it says it is a utlility with updates, notes and most things a student would need to survive H.S.

Fixing iPhone screens for cash?

I'm looking for some suggestions. I'm a 15 year old geek, living in the boonies, in need of some extra cash for spending. I'm considering fixing iPhone screens for around $50 give or take a little. My problem is this: most people aren't going to trust the average 15 year old tearing into their $300 iPhone. I'm the kind of guy that can do it - I'm techy, I've had every computer in the house fully apart for cleaning and back together and they all work better than before. I build robots from Arduino and Lego Mindstorms platforms. So I've thought of having a shop on the internet, such as Ebay or Etsy, but then I'd have to figure in shipping costs and all. The actual repair is fairly straightforward, it's about a 20 minute job, the screen costs $20-$25, and shipping would be roughly $10 round-trip, leaving me with $30 for a 20 minute job. All I'm looking for in this question is ideas for how to get the phones. I.E. Real life, having an internet shop, etc. I'm homeschooled so I have a decent amount of free time, around 4 hours a day including evenings, plus weekends.

Added (1). $20 dollar profit, not $30. Stupid typo. Lol

Added (2). Sorry, I was referring to the 4S model.

I have an old IPod Classic and I'm trying to transfer music to an IPhone 4s?

So I have an IPod Classic from 2006-07 and have 3000+ songs on it. The music is from my old computer with the iTunes library of my Classic. Right now I have an iPhone 4s which is still on version 6.1.2. I have some 400+ songs on the phone from the old computer iTunes and store bought. I recently got a new computer with an empty iTunes library and did not sync neither iPhone or iPod yet. Whenever I try to sync my iPod Classic to the new computer it says my entire iPods library will be deleted and will upload all the songs from the computer (which I obviously don't have any songs on the computer yet) on to my iPod. I don't want any songs deleted.

What I'm trying to do is put all my songs from the iPod Classic to the new computer and then sync my iPhone to put the songs on the iPhone. Is there some sort of solution I can do so my Classic's library doesn't get deleted from the iPod itself and computer? I'm worried that all my songs will get deleted from existence. Please help.

Added (1). I should also say that my old (2004) computer is disconnected and lost in my basement somewhere. Even if I do find it, it would be nearly impossible to start it up again from over 400 viruses. Which is why I got a new computer
