Mom Webs: Reliable Website Hosting for Everyone
If you're going to use a lot of photos then hostgator can be a good option as they allow you more hosting space, but it will cost a just a little more.
While you're waiting for your website to be done, you can make some plans on paper of what you want to include on your site. Good content is a must. Also you can prepare to offer an online newsletter for your visitors. A monthly giveaway or a special discount coupon code when they sign up should help you build your subscriber list. And very important as well, invest your time in learning some good online marketing strategies for your site. No visitors to your website = no sales.
