How do you know if you are hiring a real Graphic Designer who focuses on doing real design work and not just one that is just wasting time in thinking and doing nothing? For thinking that you are paying them good money for? A good place to start searching for good designers are the facts.
When you are online looking for a Graphic Designer, do a little reading. If you are searching for graphic design service then you can navigate this link https://www.inhouseprint.com.au/.
They must have an About Page, a resume or some form of credentials available on their website. If they don't, then it's time to leave the website. I do not recommend testimonials because today there is no way to verify where this beautiful comment came from.
Stick to facts and information that can be verified if necessary. If you pay hundreds of dollars or more for design services, you should see a few years of experience in the Designer's resume. Where did they get their qualification and are they really majoring in Graphic Design?
What is their work history like? Do they really become Graphic Designers at every job on their resumes? It's worth doing a little research because it's likely that you will need more design work done in the future and isn't it better to have a Designer that you can rely on?
