Web Sites & E-Mail.
It is good idea for your company to have a web presence, I can offer everything from domain registration, design of a basic web site (and on going support if necessary) and set up of E-Mail.
I have noticed that many small business have a registered domain name for their web site, but continue to use a free e-mail address (e.g. GMail, HotMail etc.). from your customers point of view it would be more professional to use your domain name. After all the facility is all ready there.
Other options can include, hosted Exchange which gives you the power of Microsoft Outlook® both in your office and from any internet enabled computer (OWA, Outlook Web Access). It is also possible to have push e-mail (subject to compatible mobile handset/smart phone).
