First off, congratulations! You have probably heard that "word of mouth is the best advertising" but how do you get that word of mouth going? Ask the customers who you have done plans for if they will give you a testimonial on your work. If they give good testimonials you can use that in your advertising.You can get low costs and design your own business cards at Vista Print. Also, advertise on your schools websites and face book, and any other communities you belong to. I work for a big 10 University and am always looking for students to hire for one thing or another. Once you continue to grow your freelancing and do a good job, the word of mouth will start working for you too.When you get the word out, be sure to explain clearly exactly what it is you can do.As you grow your business you may want to look into other resources on how to continue to grow your business online and offline. Good luck and I wish you the best in your continued education.
