Google ads

I have set up a google ads campaign but I am not sure I have got it right or that its working correctly. I need someone who knows this inside out to look at what I have done and tell me if I am being stupid and show me how it works and recommend and make some improvements etc. You have to be able to do this easily and know what you are doing. The work will be done in our offices with me in attendance so I can answer questions etc. Our IT guy is in the next office and he can help if needed. We are based in Farnborough Hampshire
