Looking for ecommerce site/advice

Im not 100% sure if this is the right place but I'll try cause the members here are so great!

I'm looking to buy/enhance an ecommerce for my wife. She is going on maternity leave, hates her job and doesn't want to go back.
I do some various IM but I'm looking to buy/invest in an ecommerce site for my wife to run and make money on her own (and some of my help. We both don't have the time and desire to try to start from zero but willing to invest a bit into something proven.
I've been looking on flippa but not sure what to trust. DP looks sketchy too and trying to sort through.

If anyone had some advice I would appreciate it. I figure a few grand to invest but trying to find legit site is tough. Something that has some real proven revenue but something an owner is tired of or too many other things on the go.

Love to hear any thoughts or suggestions to check out.
Thanks!

I'm actually trying to start an eCommerce store myself. I've already registered a Delaware LLC and gotten my IRS tax id but I'm having trouble finding a good bank to open an account with.

My eCommerce store would sell highend kitchen appliances and would be a 100% dropship operation (I won't be physically storing the products).

bank accounts and all that is usually pretty simple enough.....I"m just struggling to find a good site.

I think Prestashop has gotten a bit better. Having said that, it is an enterprise level solution but has a bit of a learning curve. OpenCart is the next option in terms of features and support. If you are branding something, like the physical products, I would go with magento or open cart. You may need a bit of assistance to get it off the ground but if you can weed your way through Microsoft office, most competent devs.
