I would say no. Giving equity means you give a part of your company to someone. Hence, you give a little bit of control of your company to someone.

If it were me, I'd give equity only to people whose engagement is vital to the future of my company. Namely, people I want to see in my company for the long term (i.e. use equity as a retention measure) and whose contributions are key to the well-being and functioning of my company (aka, not for people who can be easily replaced or whose job can be easily given to someone else).

If cash for payment is a problem, I suggest you find other ways to finance your design work. Call me if you need some ideas for that.

I wish you much success and fun developing your brand!
