I've brought that point up with the owner of the hosting company. For $400 a month I could get a dedicated server with one of the top-rated companies (rhymes with "back space").
I was paying $500 a year for the first couple of years of hosting. As traffic to my site increased, they found that it was bogging down other sites on the server. So finally they moved my site to a server that had one or two very small low-traffic sites on it.
They advertise unlimited bandwidth. Of course, the owner pointed out to me yesterday that their disclaimer, like those of just about any shared hosting company, says that if the site is consuming too many resources and adversely affecting other sites, then the unlimited bandwidth offer no longer applies.
Marcia, this is 2008. ;) Eighteen months of service goes back to mid-2006. I'd already paid a discounted fee of $237 for hosting for 2/1/2006 through 2/1/2007.
All of this started as a handshake agreement that I would do SEO work on their sites. We weren't talking specific dollar amounts or number of hours. Now he's being very hard-nosed about it. And he thinks the value of my SEO time is worth $25 an hour (a "wholesale rate," as he put it), yet the value of his hosting services is worth $400 a month, which is full-tilt retail.
Thanks again for the suggestions. I'll post again when there's a new development.
