Dear Employer,
C programmer, Systems Engineer here, with vast experience in the development of monitoring tools.
This project fits in my expertise and I'd like to help you with it.
-------
To answer your questions:
#1. Custom.
#2. Very experienced. Not related to tickets, but about reserving and purchasing "stuff" online.
Details might be disclosed in private.
By the way, is this development for ticketmaster? If not, it's strongly required to know what's the source website.
The "auto-purchase" capability strongly depends on this answer.
#3. You have my word. I can sign a NDA if you wish as well.

About the requirements:
Since you are talking about specific behaviors of the required program, I'd need to know what kind of computer is this program planned to run in.
What operating system? Local or remote machine? Multiple network adapters? 100% uptime?
I've worked with IP rotation, private and public (non-recommended) proxies. Just for your info.
>"The csv file must be in the same format as the sample provided from ticketmaster". What is this sample? May I have it?
The cost of updates cannot be calculated beforehand. It depends on many factors. E.g., the impact of the changes in the ticket seller website.
But as a very basic estimation, it has always been way less than the original cost, as far as I remember.

Thanks for reading my proposal.
Sincerely,
--DEN!
PD. Hablo Español. Por si sirve de algo.
