need design help with new radio

hi, I’m from Sydney Australia. I have designed a new 2 way radio but I am having some problems with it, I’m looking for some help, I will pay cash for your help. I need some one who has a very good understanding of battery and full workings of every part in a 2 way. I would prefer some one close but with Skype and the internet any one from any where could help. I will need some one to come to china with me [I will pay for your time and full expenses] so must be able to get or have a passport. please email me with some details about your self and experience. I am not looking for a full time employee just a consultant.
