Hello Gia,
I wouldn't recommend lowering your rates. I would definitely ramp up your marketing and concentrate on your website.
Are you getting any interest right now from your marketing that would indicate you are missing out on clients due to your rates? If that's the case, I can understand why you might think lowering your rates might help. But, if you're having trouble even getting potential clients interested in knowing more about what you can do for them, I would say your marketing needs more work.
It can be discouraging at start up to find clients, but narrowing down your niche, discovering your target market and making sure your business plan is up to date are all things that are worthwhile spending time on.
Good luck and keep us posted!
