Concentric, a business unit of XO Communications, which is a subsidiary of XO Holdings, has unveiled its new professional Web site services packages designed for small and midsize businesses. The new packages include Web site hosting, design, maintenance, and marketing.

The Web Site Design Package provides customers with site design or redesign, including 17 hours of design and production time and eight hours of maintenance over a 12-month period. The Web Site Migration Package helps companies that already have a site move it to Concentric's hosting platform. The Web Site Maintenance Package provides resources to perform ongoing maintenance or make enhancements.

"Building a Web site can be very daunting, especially for a small business. Our professional Web site services were designed to accelerate the design process, allowing businesses to focus on their core competency," Barbara Branaman, president of Concentric, said in a statement.
