Write a listening service using the Hikvision SDK

I would like someone who could write a listening & logging service using .net and the Hikvision SDK (there is a sample project within the SDK that does pretty much what we need already as part of a demo application) - My problem is I don't understand C, so I'm stumbling through it and failing miserably - if you can write the project as a vb.net application so I can make sense of it and maintain it in house in the future, brownie points.

What I need to happen once the service is started:

Service opens IP and port and listens for incoming signals

When a signal is received:
1: Service checks a table of current devices to see if the incoming IP address is related to a device we're expecting signals from.
2: If a device exists, insert a record in to a SQL Server table with all of the data from the Hikvision API, a sequential ID and the related device ID from above. I'm not 100% sure what information comes through with an alarm signal, but we'd ideally need to capture Device ID (IP), Device Timestamp, Timezone, Channel ID, Alarm Type, Local time.
3: Capture a JPG from the point of activation and name it using the sequential ID created above and store this within the file system.

Config file will need to contain
Listening IP address
Listening Port
SQL Server details

The databases don't yet exist, but I'm happy to create the full structures on our SQL Server if you want to create basics.

We have Hikvision devices here that we can either use for internal testing, or point to an IP on your network to send signals as needed.

I've got a reasonable understanding of what I need, and I'm aware that for the right person this is a very simple application; with that in mind, I'm not really interested in conference calls with your "design team" or using a software house who insist on a 300 page copy/paste discovery document. Ideally the person bidding on the job will be the person doing the work. Even more ideally, you'll be fluent in English. I've quoted this as an hourly task - when you quote for the job, please give me a ball park guide of how many hours you think the job will take as well as a price.
