If he spends 1-2 hours on a design, that's $7.50-$15 per hour. Any longer and he wouldn't be making enough to be worth his time, even in the Philippines or India. For a true portfolio, you'd want better designs than 1-2 hour quickies
You're assuming that he's going to keep this domain and brand to build a later business. This doesn't have to be forever.
Time invested is not a measure of quality.
