Hey there, how are you?
I'll be honest with you, i can definitely build you an eCommerce website with awesome features, but you will have to increase your budget, the budget you have set, is not enough for a good website, and whoever agrees to build you one, i assure you, it is not going to do you any good in the long run.
lets discuss more via chat, even if you don't have budget, i'll guide you at least, free of cost obviously.
Talha.
