Hi,
Going through your post, I understand that you need someone to research a potential product having sales velocity AND as per your given criteria like price range, profit range, product attributes, keyword search volume, seasonality etc. I use different paid tools for analysis like helium 10, jungle scout, viral launch, merchant word etc.
Looking forward to hearing from you soon and waiting anxiously to get more product details to start working on it.
Cheers,
Syed.
