Unless you or someone within your business is a graphic designer or has in-depth knowledge of design software the wisest thing to do about designing your logos is to outsource it.
If you have some software experience like Adobe Photoshop or Microsoft Paint it might seem prudent to create the logo yourself and save yourself the cost of employing a one-off designer. However, bear in mind that cost isn’t just measured in dollars and cents, and the time it will take you to design and edit any new logo will soon add up to the point where it detracts from other, more critical tasks.
There are several platforms where you can find excellent, value-for-money logo designers. The most obvious is Fiverr where some designers will create you logos for just $5 each.
