My apologies. As stated in the first post I will be starting with one of the t-shirt campaign companies. (Techie, Teespring, etc.) Depending how this goes then there is a possibility of doing own shopify store or something. With the t-shirt campaigns I do think you can sell internationally so that shouldn't be a problem but I'll double check.
50 shirts nets about $574 with the campaigns. Like i said after taxes split is a little more than $200 for you. I will also reimburse advertising costs up to $50 dollars.(must sell $50 t-shirts tho)
If you decided to use more advertising but sell over 50 shirts than we can work that out with a higher reimbursement.
Depending how well this goes and how many people than I may start giving the $50 upfront at some point.
My roommate makes the designs and we take the same cut. So that around $200 in your pocket and $150 in ours after reimbursement for advertising.
The question then is: Why is the person selling the t-shirts coming to you?
If they know the target audience well enough to convince them to buy t-shirts, they should know them well enough to understand what t-shirts they'd be most willing to buy better than you.
At that point they could just post a 5-10$ bounty to design the image on Bitcointalk if they are not capable of doing so and bam, they can pocket the 570$ instead of 200$, instant triple.
What makes it better to go through you rather than teespring?
(One more thing I forgot: You could just run away with the 200$, you have no reputation here to speak of. If the seller used teespring directly, they could actually be more sure they wouldn't get scammed)
