If your work is amazing then you don’t have to run ads on social media. But if you want to because you want to get high end clients then show your work off.
I run $1 a day and it gets me $300,000+ jobs. Because I do good work and my customers love the work it’s easy.
Do something that nobody else is doing. Get creative!
If you want high end clients then do something worth their time. Charge more money so that low end clients will stay away from you.
