A friend of mine asked if there's a market for tall, burly, bald guys in their 40s. I've been looking through some portfolios here but was wondering if anyone has any input. Thanks in advance!

i would say desire sure, especially in stock.
But market, as in, expecting to get paid, not really.
Unless he is really really charismatic to sell watches etc.

Grizzly Magazine! 

all right, so I think your friend might be looking at this from a somewhat incorrect perspective - does he LIKE modeling? Does he want to give it a try?

OR does he think he'll make some extra bucks with it?

Because - sure, maybe he could do some stock of pose nude for art schools. Or he could join an agency that covers the "ugly" (notice I'm using this sarcastically) models. This is a niche market also so chances of becoming rich are slim.

Or maybe he could do fittings for some plus size clothing brand.

I think the real question here though is whether or not he wants to give it a try for FUN and take it from there...

Thank you for all of the comments! I'll be passing along the advice. Very much appreciated!

Probably not much more long but has he considered Extra work for film and TV?

There is, but it's seasonal.
