In which country to incorporate an upwork agency?

[kurumbus]

Hey folks.
So I would like to create an agency on upwork and incorporate. 

• I would need it to be able to work with upwork and Payoneer (I guess). 
• I would need everything to be done remotely cause opening a bank account in person is not an option (for obvious reasons lol)
• Obviously I'd like lower taxes since competition is rather stiff here. I guess most of my income from clients in the US and EU I suppose (and not sure how offshore income rules work). Also, I've read that Upwork Escrow is a Delaware LLC -  does it matter? 
• I'm a Russian national so I guess it limits my options somewhat

As I understand my options are HK, Singapore, Estonia and smth like Delaware LLC? Am I wrong?
