Pro studio could be jumping ahead at this point. But, I believe in supporting the dreamer and the dreamers dream. To me that's the most important part of this whole story. Dreamers are often not practical and that's okay. In fact that's a good thing. If Keegan has worked to save money for a certain goal then he is learning to set goals and support those goals financially, creatively and otherwise. If he spends all he has on this and gets it done he is way ahead of many others who don't take chances. A 6 tune instrumental CD of any kind just might be the thing that encourages him to go deeper, dream bigger, be better. It would certainly be something to be proud of. Especially at a young age. If he spends all he has, goes broke and the whole thing flops; I, for one, would be extremely proud of him for going for it. And, if he stays encouraged and presses on he will be all the wiser and that much closer to his dream. He can and will recover financially. Let the dreamer dream and let him go for it.
That said; it would be wise for him to listen to some good, practical and encouraging advice. Dreamers need some balance from family, teachers, roll models, other musicians, etc... But, we don't want those people who care so much to squash our dreams.
If DIYS studio gets in the ways of creativity then I'd minimize it or get it completely out of the way. Let him focus on writing, playing, collaborating, performing, studying...
Perhaps a semi pro studio like many of us on this forum and others could help take a first step to cutting a few demoes. Or, find someone local to him, pro or semi-pro, that will let him take a walk through or a few hours in the studio. A real pro studio IS going to take his money and he and his bandmates might not be ready for a hard pus on their skills level at such a young age. A good home studio semi-pro can get very Youtube worthy tracks for him along with CD, MP3 and even video.
On the practical side think of a NASCAR driver going 200 miles per hour. He probably started out racing Go Carts as a little kid.
Keegan, you go man! Be encouraged by any advice you get. Never get discouraged no matter what the adults tell you. If you want to go full studio big right from the start then go full studio BIG! If you don't you can always do later and then you'll have even more experience and more songs.

Does the noise in your head bother me ?
