If you are doing an professional ICO, then you might want to skip AWS and for example invest on a dedicated server. If you are doing an ICO, you should have some budget to start with as it is unlikely that VPS's are that reliable if you get alot of requests on your servers.
I'd atleast try
Godaddy, as they have always providen quality services to their customers.
Although last but not least, why are you making an ICO if you don't have a specialist plan about such things?
