Hey, I haven't been on this forum too much, but one hosting company that's reliable to me the past couple of months has been HostNetway.com. For $35 I got 300mb of storage space, and 15gb of bandwidth, which is more than enough for a business such as your own. This $35 dollars excluded a domain name but it's all for one year, which is rare to find!
As for you business I agree with Subversive, charge what you think is best fit for the work you put into it. Usually you should start out cheaper so that you can build a nice portfolio for customers to view. Most of the time the only thing that lures a customer to purchasing a service from you is from a portfolio, whether it be banners, logos, web designing, etc. That's all I can think of right now and good luck to your business.
