Are you a MailChimp ninja!?!?!
I'd like to find someone that really knows the ins and outs of MailChimp that could work with me so I can start to use it efficiently and effectively for my website. This would include an initial phone call (so it's probably best that you're American, as I'm located on the East Coast of the U.S.) where you'd walk me through the basics, and I'd tell you a little bit about what my website is, and how I'm looking to engage my users.
(It would probably be a good thing if you're good with design as well, so I don't need to hire someone separate for that, but no worries if you aren't.)
But in terms of putting together your bid, assume that you will be providing me with two hours of "MailChimp tutorial services," and that there may be a chance for follow-on work after that (and I may just have you run the MailChimp component of my site altogether).
I hope I've been specific enough with what I'm looking for... my apologies if I haven't been!
