You seemed to contradict yourself in saying it will be invaluable experience, but they'll be able to do "as good a job". All I'll say is I am fully aware of the impact of design, and, however biased it might appear based on my position, I'm aware of it because I can see the results.
I have no problem in someone new to the forum being given a helping hand and so on, but I won't put any money into something I know won't achieve its full potential. Besides, small businesses can even contribute what you'd be asking for if enough came together. I've spent over £2000 in 3 months on copywriters for 1 of my companies and I'm a "tiny" business.
But, I will leave it there. Not here to spoil the fun, just give honest comments on something I work on. And if Eagle wants to do it for free, it might change the scenario around.
