I am creating a medical transcription website. Since I will be charging my clients per minute and per hour, not per report, I need to create a transcription cost calculator that will allow my clients to calculate the total price per report. However, in order to add the calculator to my website, I need to create the HTML, and I do not know how to do this. The cost calculator would need to look something like this:

Minutes of recorded audio (a window would be displayed here, where the client can indicate the number of minutes of their report (from 1 to 60 minutes).

Hours of recorded audio (a window would be displayed here where the client can indicate the number of hours of their report (from 1 hour to 60 hours).

Total cost (here the total cost of the report would be indicated).

Any help would be greatly appreciated!
