Hi,
I read your project description and saw the picture. I think this is a simple project. But if you are to include 8 seven segment displays as described in the picture, you may have to have use decoders ( serial to parallel converters). It would require a small PCB.
During the past 3 years, I have invented many embedded devices which uses Arduino, PIC and Android. I have a sound knowledge in Arduino boards and Shields. I had been part of inventing Arduino based robots and embedded devices. Various modules, sensors, actuators, relays, servo motors, LCD displays, PWM, ADC, user inputs and outputs have been used in those projects. Firmware of those devices vary from simple to complex.
ALTHOUGH I am not in London I can provide all the support to finish this project. I can provide you with 'well commented - clear to understand Arduino code' and tested PCB, recommend suitable components and help with troubleshooting.
As I'm looking for reputation in freelancer.com I value your positive reviews more than anything. That was the reason why I have posted a reasonably low bid value. But that doesn't mean any compromise in quality of the work. I can assure you that I can complete your project within the time-frame. You may contact me to discuss further.
Kind regards,
Akilan
