Dear Sir or Madam;
I have read your post and I'm sure that I can be helpfull because the I know very well all the topics concerning Amazon managment.
Let me start explaining my proposal based on your post requirements and list some task that I can do for you:
1. Creation and edit amazon listings (all the marketplaces) based on popular searches, keywords, top search terms (longtails) and best sellers common phrases.
2. Checking and Updating listing info like prices, stock, variations, etc (each marketplace everyday)
3. Managment FBA stocks.
4. Products comparison & Market research.
5. Create and manage Sponsored Products or Brand ads.
6. Reporting of traffic metrics and sales conversion.
7. Customer support by Amazon message platform, and more.
In essence, I'll be in charge of all the managment processes of your account from mondays to mondays (a few hours on weekends "Only fo Customer Support and Solve marketplace issues")
As well as manage another marketplaces accounts like eBay, Cdiscount, Afound, Fnac, El Corte Inglés, Ozon, Emag, La Redoutte, Next, and some more specific marketplaces.
About 3 good things about me, well I can say I have an strong experience in Amazon managment, I'm a very fast worker and I have some financial skills (I'm Bachelor in Business Administration); and 3 bad things about me, I'm not total fluency in english (I'm in on-going training), I'm new in this platform and surely I will not the cheaper bid.
I look forward to hearing from you.
