I recently recieved a job doing a ballet portrait and performance, seperate days. I want to think the person that gave me the job, they havent asked for a % of the sales, or anything. I want to do something nice as a thank you, this may also help me get the job for the next one. I was thinking about putting aside 10% of my profits to use in marketing, so I could use some of that money for this. I was thinking maybe a gift card to a nice resteraunt, or a basket of fruit or something. Whats normal for this sort of thing? Thanks for any advice.
