Build a Jquery Timer

I'm looking for someone to build a single-page standalone Javascript / Jquery timer with an HTML interface. The logic takes a little while to understand, but the functionality itself is very simple and does NOT require any stored information between pages or any AJAX. WHAT IT IS: This timer tracks the food consumption of a creature from a video game. Once started, the timer shows depletes at a predefined rate until it reaches a predefined amount of food. In addition, it will indicate when the creature will starve (if applicable). HOW IT WORKS: Users can enter a CURRENT FOOD and a MAX FOOD. When the timer starts, it depletes CURRENT FOOD at a pre-defined rate until it goes through a pre-defined REQUIRED FOOD value. A meter displays the timer's progress. Example: CURRENT FOOD: 50 MAX FOOD: 100 REQUIRED FOOD: 200 Timer must go through 200 food. 50 has been already been consumed (MAX-CURRENT). Timer starts at 150 out of 200 (75% remaining). Timer finishes when it reaches 0 (CURRENT FOOD will be at -100). A pre-defined STARVE value indicates how much FOOD must deplete before the creature starves. This is simply indicated on the meter as an "UNTIL STARVED" label. If the STARVE value is higher than the MAX FOOD value, it is not displayed because the creature will not starve before it reaches UNTIL TAMED. Example: MAX FOOD: 100 REQUIRED FOOD: 100 STARVE: 50 A "UNTIL STARVED" indicator will be displayed halfway through the meter (50 / 100 = 50%). Users can enter an "ALARM" value. This will simply play an alarm sound once the timer reaches X minutes before the REQUIRED FOOD is met. (Or UNTIL STARVED, if it displayed). IMPLEMENTATION REQUIREMENTS AND NOTES: - Full project specifications will be supplied. - Project must be built in Jquery and Javascript. No added libraries. - A fully functional timer can be found on the iOS and Android app stores ([login to view URL] [login to view URL]). Their functionality will be exactly the same and can be used as a reference. - I have this timer completely functional in React Native (JavaScript), but because of the nature of React Native, the code snippet I will supply won't be functional since there are many other connected parts throughout the app that require it to run. Also, React Native is structured entirely differently, but since this is javascript, some of the code and functions can be reused with some modifications. At the very least, You can also use the code to understand the logic. - The HTML and CSS is built. You just need to build the Javascript to run it. - The final product will be deployed in a similar way as this timer: [login to view URL] -- some code and logic can be reused from this timer.
