Sometimes (most times) the search feature is problematic. I searched "cadlink" and nothing came up, cadlink.com however went right to you. I have found that tends to work better use the site.com minus the www. and you can usually find what you are looking for. I then tried "cadlink" again and all related sites popped up.
As far as "CADlink" vs "cadlink" in the listing, your company is shown on the site as CADlink so that is how it is going to be listed. We title the sites using the given name the site presents. No more, no less.
Can you change the listing and how? Possibly. You would have to rename the company on the site to cadlink vs CADlink, then go to the category in which it is listed and choose the update listing link near the top. This would cause an editor to look at the site, review for content and changes, and make any changes needed. However, it could also result in the site be placed back into the unreviewed pile until someone had a change to thoroughly review the changes and rework a description.
My suggestion if it ain't broke, don't fix it.
I did a quick check for you on three search engines and in all three cases your site was returned at the top of their lists. Seems to be working fine as is.
Thanks.
