My team's skill set were similar to many efforts of sub contractors. So by managing & refining my team's tasks I was able to replace the work done by the subs.
Managed Yellow pages spending >50k$ annually. Modified and refined ads and worked with department managers to monitor traffic sources. Gradually worked down spending to $6k annually.
Reduced Ad agency tasks & I am also a graphics artist.
For our direct mail campaigns, I did it all, from concept to mailing lists to delivery.
I created company newsletters.
I found TV ad content that was of higher quality and lower cost than was locally available.
Decades of self employment has taught me how to negotiate. Negotiated contracts and purchases for everything. (technology, marketing, construction)
