I have been building a fairly complex D7 site (for me, at least), for a local nonprofit. The site has some Drupal Commerce stuff for membership and classes, and some fairly extensive membership-related functionality, including a variety of membership reports with attached CSV exports, lending library management, member ads, forums, various calendar features, and more.
Some complex content types. A variety of Roles, and roughly 400 Permission rows. No custom module development, but custom theming based on Omega. I've spent an appalling (and embarrassing) number of hours on this thing (hundreds). If anyone is interested enough to want to actually take a look at the current dev site, I can provide the URL, but I don't wish to publish it here.
Here's my question: if such a site were professionally contracted, what sort of very general ballpark figure range (or minimum) do you suppose might be likely? Anyone care to venture a stab? This isn't for any sort of billing question, just as a point of discussion.
Thank you!

Hi David
Love the design on the chairs! Great work, i did not even know about chair art.
i do not think You will get anyone to talk prices especial from a big company. But pricing needs to be discussed for the consumer.
It sounds like a pretty extensive site i would be around 15k but a large firm would need to charge around 30k
Similar site
I am working on a very similar site - Classes, memberships, commerce, as well as a ton of social aspects, groups, and customizations to profiles and content types. I know I am undercharging but so far have been ok with that as it's been a learning experience. But it is nice to know that something like what I'm doing would be in that range.

Thanks very much for
Thanks very much for venturing those numbers, @MarketStone. Took me a moment to get your chair reference, but thanks on that, too!
Anyone else? Please, oh pretty please?
