You can't market your company without the right tools any more than you can make a computer run without the right software.
Don't hesitate to use the services of a good IT copywriter. Then let him or her put what you must communicate into the right words. The investment can pay you back quite well even on a tight budget.
Look for someone who is independent to avoid the higher costs of an agency or large design firm, and who works in tandem with a designer. Before your first meeting, make a list of all the tools you think you'll need--even if you can't afford to create them all right now. That way, your copy and design team will conceptualize them as a cohesive family of tools.
Question added to topic Marketing • September 8, 2008
How can I market and grow my 8-year-old IT business?
I have been running my IT company for eight years. I can sell clients when I get in front of them, but I have no marketing materials. I don't know how to put my services into words, and I have a very small budget. If I am able to get more clients, I could spend more on marketing. The site looks awesome.
