Weddingbee boards

Hello Bees, it's me yet again with another question. I thought I'd cast a wide net with this one.

When I first started this planning process I knew right off the bat I wanted a DOC. So I started emailing around and meeting with people. I was surprised to find some charge upwards of $3000 for their services. Yikes! I certainly didn't have that kind of money. I really liked Janel w/ Occasions and she charges at least $1800.

After doing some research on the knot and here a few more affordable DOCs came up including: Manette Grace, Christine Heidel, Laura Gram, Emily of Exquisite Events, Teasha and Shannon w/ perfection is planned, Bobbi Roth.

Now I'm even more surprised and confused. Why the big difference in prices between gals under 1k and more expensive DOCs?

Has anyone worked with Janel from Occasions, of all the planners I met, I liked her the most.  Granted I haven't met any of the more affordable DOCs yet.
