Yes I do, in fact I prefer to work this way as working 'with' someone is a two way process. I don't accept all work as results will often only come with co-operation. In most cases you will know far more about your service or product than I will. What I know is how to market online and how to get the best from the algorithms but it will take your business and sector knowledge to help understand the target audiences. I will be providing ideas and strategy to help achieve a good ROI but I can't do it alone.
If we are to work well together there must be a good understanding and a desire to want to succeed.
