Advertising Design is the most important point of advertising. If your advertising is designed poorly, who is going to pay attention to it? The answer is nobody will. The Design will in most cases be done by a professional designer; there are a lot of companies out there that will design you, logos, banners, posters and anything else you can think of for advertising. These companies that specialise in advertising design will charge you for their services.
Depending on the reputation of the company, depending on the quality and the standards of designers will all contribute to what the Advertising cost will be. You will find companies that do offer this service at a low price, but be warned, they may be that price for a reason, check out the companies first, find out if you can see some examples of their previous work (if they have a website it is likely to be available on there, if not you will be able to request some) and look for customer reviews.
Posters
Advertising Design does not have to be performed by a professional though, a lot of companies design their own logos, and posters. It is important that your logo is appealing to the eye, vibrant and something that you will remember. Simple designs are often effective designs; do not feel that just because you have put a lot of detail, a lot of images, a lot of text into your design that it makes it good. Less can often be more and as long as it catches the eye and gets to the point, your advertising will be successful.
