I recently wrote a script to simulate some web transactions recently (not too different than yours), I had good luck following this tip from curl's website (hxxp://curl.haxx.se/docs/httpscripting.html):

4.5 Figure Out What A POST Looks Like
When you're about fill in a form and send to a server by using curl instead
of a browser, you're of course very interested in sending a POST exactly the
way your browser does.
An easy way to get to see this, is to save the HTML page with the form on
your local disk, modify the 'method' to a GET, and press the submit button
(you could also change the action URL if you want to).
You will then clearly see the data get appended to the URL, separated with a
'?'-letter as GET forms are supposed to.
If there are 3 clicks, then there are going to be 3 separate curl commands. You should be able to avoid the first "click", because you'll just be uploading the file in step 2, no need to browse to the first page once you figure out the URL of your POST.
I'm making up examples in as I don't know what your actual HTML form looks like. The trick is figuring out the form query variables (order matters!!) and converting that into your curl command-line arguments.
Code:
#/bin/sh
# 1. Get page - probably not required
curl http://www.mysite.com/mypage.htm
# 2. Upload file - most likely a multipart form. the '@' means upload a local file
curl -F "upload_filename=@/full/path/to/local/file.txt" -F "myotherqueryvar=queryvalue" \
-L http://www.mysite.com/upload-page.htm > html_out.htm
# 3. Parse HTML - you'll basically have to look at the return page
# and see if you can figure out a pattern that will grab the link.
mylink=`grep (insert pattern here that will get your link) html_out.htm`
curl ${mylink}
Not sure if you can just supply the actual website... might be easier to give you the exact commands.

curlopt_resume_from
CURLOPT_RESUME_FROM(3) curl_easy_setopt options CURLOPT_RESUME_FROM(3)NAME
CURLOPT_RESUME_FROM - set a point to resume transfer from
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM, long from);
DESCRIPTION
Pass a long as parameter. It contains the offset in number of bytes that you want the transfer to start from. Set this option to 0 to make
the transfer start from the beginning (effectively disabling resume). For FTP, set this option to -1 to make the transfer start from the
end of the target file (useful to continue an interrupted upload).
When doing uploads with FTP, the resume position is where in the local/source file libcurl should try to resume the upload from and it will
then append the source file to the remote target file.
If you need to resume a transfer beyond the 2GB limit, use CURLOPT_RESUME_FROM_LARGE(3) instead.
DEFAULT
0, not used
PROTOCOLS
HTTP, FTP, SFTP, FILE
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com");
/* resume upload at byte index 200 */
curl_easy_setopt(curl, CURLOPT_RESUME_FROM, 200L);
/* ask for upload */
curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
/* set total data amount to expect */
curl_easy_setopt(curl, CURLOPT_INFILESIZE, size_of_file);
/* Perform the request */
curl_easy_perform(curl);
}
