The membership fee seems really high for a slack channel... gives it more of a job board vibe than the work-trade club vibe that's implied by the domain. Sure, it's maybe worth it if you don't have a job and this will get you jobs (but I'd be skeptical that a jobless creative would sign up for a $30 monthly fee job board). Seems like the fee would filter out applications from more talented people who have a lot of incoming work requests already but would be curious about a more curated channel. Idea: only charge for posting $$$ jobs (like craigslist) and focus on getting a roster of super talented members.
Who would pay 30$ a month for this? It seems almost insane that you thought "hey I am going to make a slack channel and charge people an access fee of 30$ a month". "Max members 1000". So you plan on making 30k a month for creating a slack channel?
Interesting that the promotional quote for Tradework is by Clark Dinnison,Founder of Noon Pacific, and the share url on the Tradework entry form directs to <a href="https://noonpacific.typeform.com/to/hcWhV7" rel="nofollow">https://noonpacific.typeform.com/to/hcWhV7</a>
