Hi there,
Firstly, thanks for taking the time to read my proposal!
After reading your Project Description I can see you are just getting started with your store, and I feel your pain, it can be a minefield and done wrong can end up costing you an absolute fortune, thankfully there are people like me who can help you avoid falling into this trap.
I've just joined Freelancer, so just feeling my way around the interface at the moment, so apologies if I get something wrong.
To give you an example of my past experience, and reassure you that you can indeed generate a lot of sales using adwords, a previous client of mine was earning around £150 per month via his ecommerce site, within 4 months of using adwords, we had his business generating sales of £7500 per month, needless to say he was over the moon.
He was just one of many, and aside from setting up an adwords account I can also advise on other areas including seo and social media, as well as facebook Ads, to give you a rounded marketing strategy.
I am Google Adwords Certified, Google Shopping Certified, and also a Google Partner, and I would love the opportunity to work with you and help you get your business to where it needs to be.
I can start asap,
look forward to hearing back from you,
Chris
