Small thunderbird extension project

I'm looking for someone fast who can churn out a thunderbird extension 
for me on a low budget.  Developer would of course have the freedom to 
publish a general purpose variant of the extension as their own.

Here are the details:

We are an auto brokerage, which in case you aren't familiar is basically 
an auto-buying service.  ("It takes the pain out of car buying." 
<laugh> :) )
   Basically we receive referrals from Credit Unions and specific 
inquiries on new or used cars, and our brokers go and find them.  Our 
website is www.cu-autosolution.com.

We use thunderbird as our email client at the company, with all of our 
employees accessing their mail on our local mail server through IMAP. 
Management here wants all email reviewed before being distributed, so I 
have set up a forwarder on the mail server that dumps all mail addressed 
to our employees into a Staff Account that I use as the default mail 
account at my machine.  I have added every employee account to this 
machine as well, so after reviewing mail, I simply select the email and 
move-to [Employee Inbox].  We get away with this cheap and simple system 
since there are so few employees (~10).  (Before I got here a few months 
ago they were printing all emails and placing them in physical inboxes.)

There are two types of email that have specific "needs" associated with 
them.  These are the inquiries and referrals I mentioned earlier. The 
business requirement is to log all of these, which allows for mining 
some basic information and determining to which employee they've been 
distributed to.  This allows management to do simple things like figure 
out how many referrals a broker has received from a certain credit union 
in the last month.  In addition to logging them, it is necessary to 
archive a copy of each email logged.

I decided earlier today that I would learn how to write an extension for 
TB that would take care of what I want, but upon investigating I 
realized this would be better suited to someone who has experience and 
can hack it out quickly, since I'm currently involved in a database 
project for the company that is consuming all my time.  So here's where 
you come in :)

Here is what I envision. (Or something along these lines):
A button located on the main toolbar will perform an action on an email 
or group of emails.  This event will open a window that will contain a 
preview pane for the email, a few option controls that will determine 
type (referral or inquiry), destination (employee), etc, and several 
data entry form fields that will collect the basic information about the 
referral or inquiry.  After the user (me) enters the pertinent 
information, a "Send" button will.
a) output the field information to a text file
b) send one copy, marked 'unread', to the selected mailbox
c) archive one copy (move it to an IMAP folder)

A few notes:
-Performing the action on multiple emails might add a layer of costly 
complexity, so it's not necessary.  But what I was thinking was that 
implementing it would just pull up (n) modal extension windows stacked 
right on top of each other, but I don't know how and if this is done.

-To reiterate, the reason I've imagined this as the solution is that my 
manager wants to be able to perform these actions in my absence, and so 
far she's had trouble remembering the right-click, move-to inbox action. 
  This is why I want the solution to be extremely simple.

-I'm looking for a quick and dirty answer, since the company doesn't see 
the justification for spending money on IT solutions, and any solution I 
create for them has to be useable by them.  (Right now I'm still 
printing the emails out and then typing the information into a 
spreadsheet at the end of the week per their instructions.)

-If the project is sufficiently trivial, an extended capability would be 
to automatically grab some of the form information from the email body 
where possible, since the majority of our inquiries are created by 
webforms and are therefore consistent.


So finally:
If this is an involved project, the cost won't be justified.  From what 
I read about the mozilla framework, this should be pretty simple.

I look forward to hearing from someone.
