Get me quality traffic

I am running a test business to:
(1) Test the viability of a particular business model
(2) Find a dab hand internet marketer who can get our more ambitious projects a large volume of customers at a reasonable acquisition cost

The test business is mobilesitepro.com.au which will build mobile websites for customers. Ideal cost per acquisition is $50. I have exceeded that markedly.

At the moment, I've done the following online:
(1) No SEO
(2) Adwords - setup 50 keywords based around mobile websites which have generated 0 sales at a cost so far of $220

Ideally you will:
(1) Show brilliance in using the best internet marketing techniques to generate traffic after which our optimised sales pages will turn visitors into customers
(2) Provide case studies of previous clients you have provided great results for
(3) Ask the right kind of questions which will assure us you know what you are doing
(4) Be able to scale the effort as we are spending small, but once you can show repeatable results, we will scale fast
