Hi,
I have been working on Online Advertising and Marketing for almost 4 years now. I have set up accounts of more than 100 advertisers, including Fortune 500 companies like Target, Best Buy, Fossil, OfficeMax etc. So this should be fairly easy :)
Here is what I propose to do - I would want to replicate your website into your account structure. Basically, build out campaigns for each category of products or services you offer. This allows you maximum flexibility and easy management as you can see what is performing and what is not, and decide your future strategy based on it. I can build a skeleton structure for you if you can let me know your website.
I do this day in and day out. I am very confident of my ability to deliver high quality work and would like you to trust me with your assignment. I will be happy to share a free sample of what I can do for you, before you choose me as your freelancer. Hope to hear from you soon.
Cheers,
Ankur Lodha
