Build A website - Timer

Hello, We have a timer we want some one to create a timer for us it will be simple the timer is completed just need to make it dynamic the basic thing will be timer will be stoped every day at 4:20 am or 4:20 pm and will resume at 4:29 pm or am both cases. But the main thing comes here time will be getting from the users local time not from the server time make sense like when ever user logs in it will show hours remaining till 4:20 pm or if 4:20 am is coming then wil count hours till 4:20 am make sense ? Budget $10 to $25 Thank you
