custom externals ?

[Hershel Fisch]

I looking in to have a custom made external for mac & win. to send 
emails directly from RR. in detail, from a contact db to take a given 
fld to put it into the "To" fld , another fld to the subject fld and so 
on to the default email program.
Yes I am aware of Sarah's email stack , 1:  thats only for receiving 2: 
I think its easer to write an external then to rewrite a full email 
app. (thou it would be a nice thing to write a full email app. in RR)  
I just need it for sending multiple emails and receiving emails without 
any special needs.
my question, how much would it cost me an external like this ?

Also an external to fax directly from RR using either FaxSTS , WinFax 
or such, would be nice thing.
