I need a Freelancer to design a circuit that can blink 50 LEDs at a speed of 1Hz adjustable up to 10MHz or more.
Adjustable resolution of 1Hz steps.
LCD screen to display frequency.
Buttons or dials to adjust speed.
1 button for Hz, 1 button for MHz?
On/Off button or switch.
9 volt operation for prototype.
a 12 volt model with no LCD screen,
12v model should work only on a programed frequency. Not adjustable.
12v model should power 100 LEDs, in two sets of 50.
I build my own circuit board and prototype.
No milestone payment until prototype is working.
I have paid Freelancers before that collect money and provide broken design that never works so I will not pay anything until it works.
PIC chip is ok and preferred. =)
Thru hole components preferred for prototype.
SMD components are ok for resistors, transistors, diodes, capacitors, but NOT for IC or PIC.
Thru hole only for IC and PIC.

What about an AVR? When you say no milestone payment, you mean no milestone release or you will not even create a milestone? (because I think that's very unfair)
