Thank you for asking.

My code took one year to be totally developed. However it is simple. I could rewrite it in Java, C# or any other language.

About prices... I think to ask for 0.001 per week for 1000 queries/day. If you want to use 5000 queries/day, it would cost you 0.005 a week.

For sure I can let the clients test the service a few days for free.
