Hi, I'm a data analyst who loves automating data processing. Your project looks interesting and I'm keen to help out. I'm not sure why all of the other bids are so high, but this looks to be straightforward.
The etimspayments system uses a simple POST request to check against their server, and I can automate this for your list of licence plates from a csv file. I am not sure if the date of birth is required or not, as I don't have a working example to check (do you?). Even if it is, provided there isn't any limit on repeated requests, I can have my program run through the year of MM/DD combinations without any issue. Again, I can't tell without trying a real-life example.
I am happy to host the tool on my own server, and can provide a simple password login for you if you like. If there is a rate limit on the queries, I can have my server space the requests out and email you the results once it's completed.
Please contact me to discuss further. Regards.
