Hi,
I'm sure you don't feel like reading anymore of these! So I'll just get right to bottom line.
I can 100% help you out w/ ebay. I've been selling, buying, trading, etc on ebay for 20+ yrs. Each month over the last 3 years, I have averaged 5 sales, even more offers that I was able to turn down. I know ebay inside & out (all aspects). And I can help you setup your items you would like to sell, it doesn't matter what type of items, w/ just a little research & a few clicks, I'll be able to tell you how many, when, how much & a ton of additional info on items that you're selling or items that are very similar in the past week, month, 60/90 days. You will be able to see what you can expect, how popular these items are, what is the bidding activity like, etc.
Also, I'm in digital marketing & I have an ecommerce store that started from just selling via ebay. I now sell direct through my store & save on ebays costs, get more repeat customers & sell items faster (also sell/buy & am very familiar w/ amazon, craigslist, & all the current top smartphone apps for buying/selling (i.e. LetGo, OfferUp).
So if you want to figure this out w/ no hassles from someone w/ real experience & success, I'd love to help you out.
Thanks for your consideration, take care
Aaron
