Coming up with a business plan and creating a flashy website is the easy part of starting a business. The hard part is building the product and making sure the public is aware of your business. A business card does the former, and brochures can do the latter.
You can get a business card done cheaply in an online printer from templates you download, use as a guide and make your own, or buy pre-designed for a few bucks. It all depends on what you're wanting to do.
Some companies give you free business cards. However, I recommend buying them with your business's logo, tagline and even a short description that's relevant to your business to be printed on the back.
When you're buying cards from a stock company, they'll give you the cards with only their company name printed on them, plus the templates you downloaded from their website. In my opinion, it's much more informative and professional if you can also find out what they are as a company and what specialties they specialize in.
It's just like a website. You don't wanna use the same boring, generic websites that everybody else is using. On the other hand, you don't wanna start a business with a blank canvas.
It's not that expensive to buy business cards online. A lot of the companies offer you a design which you can customize, download or buy from them.
It's wise to look at what other people have designed or what they're doing, especially if you want to do something similar to what they've done. If it's not something you can do, then it's probably a good idea not to do it at all. If you want to follow the way other people are designing their business cards, then it's probably wise not to get too creative. You don't wanna put too much on your business cards.
So when you're looking at a stock company's website, you want to do it carefully. If you feel you can incorporate some of their ideas into your own business card, then it's good for you to go with that. If you wanna do the exact opposite, then it's not such a good idea. But keep in mind, your choice is gonna have a huge impact on how many people notice your card.
