Don't conflate all "work for credits" as being worthless.
'Love Is Blind' was "sampled by 30 million member households."
If your business's demographic would be in a similar cohort as the show, then this work could be used to project authority. I know of this show. My wife does.
If a local photographer demonstrated that they were in the show, their work is great, I would find them interesting. I wouldn't blindly give them my business, but at least they don't blend in like 100's of other photographers.
If you can't envision exactly how you would use this as a promotional piece or blindly expect that just by doing the work you'd get a magical windfall of additional business, then this isn't for you. Don't sign.
>Another little dirty secret: bylines in your website don't mean shit. The money comes from networking.
Empty bylines? Sure. But a byline that states your competency and goes on to display that competency by supporting it with 1) beautiful work and 2) having well known clients? That helps to solidify the case of why they should work with you.
"Feel free to reach out to any of my previous clients. I will give you their contact info if you need a reference or two before working together. "
