So I asked myself. What are the various companies and how do they compare?
While this is hardly a comprehensive list, I tried as best I can to find as many services as possible for you to peruse. Each service is slightly different and I also tried to highlight the things I felt were important between them, though they often have widely varying services, like Goddess Fish will make book trailers and Worldwind will make tour graphics for a price, even if you are not touring with them.
So, without further ado...
Bewitching Book Tours
This company seems to be able to hand a large quantity of tours at the same time with an impressive number of tour hosts. Specializing in paranormal, urban fantasy, and paranormal erotica. This company does a pretty decent job with the tour buttons. The site does not make any guarantees about how many book reviews you'll get because it depends on host participation, only the number of blogs you will be hosted on. It offers a variety of different types of posts. Includes tour buttons in packages.
Tour Packages Range from $35-155
Enchanted Book Promotions
I also like the tour buttons this company does and their new site is so much better than their old one (which looked like it was designed for a five year old obsessed with Disney Princesses). Includes tour banner in packages.
Tour Packages Range from $19-249
Goddess Fish Promotions
Not overly enthused with the quality of their banners. They specialize in romance fiction (in all its sub-genres: fantasy, suspense, paranormal, historical, etc), other genre fiction (mystery, SFF, etc) and Young Adult / Middle Grade fiction. Includes tour banners in packages.
Tour Packages Range from $30-225 (With Book trailer)
Worldwind Virtual Book Tours
The one day includes a $50 Amazon gift card, which will be raffled away as part of the package. The packages don't exactly match up with some of the other sites I've reviewed here. The $130 package is 15 tour stops in 1-2 weeks. Packages include a tour banner, which are among the best I've seen. This is a brand new company, but I really like their banners and there's no limit on the number of stops for each package. That's the minimum stops for your tour, which is unique and is one of the reasons I like this company, despite the higher price point for their tours.
Tour Packages Range from $100-260
Packages include tour graphics. Single cheapest package.
Tour Packages Range from $15-70
Virtual Book Tour Cafe
Packages include a static banner.
Tour Packages Range from $35-360
TLC Book Tours
I'm not overly fond of their website as they do not list any rates on their site. It doesn't say anything about other forms of promotion. They focus on book reviews and getting books noticed by book clubs. I can't, honestly, see a lot of new authors choosing this options.
Tour Packages Range from $549-1456
These last two had no information on their sites and I never got responses from the people involved so...
