I normally design simple websites online using the online design facilities provided by Bravenet. I now want to start designing professional data-based e-commerce community websites for banks, higher institutions, etc, online. Is it possible. Are the facilities for such design available online at Bravenet? If so, how do I start? How do I do it.
Thanks.

e-commerce community websites for banks? That would be the Advanced Wizard, I think.

No, sorry. Optimism is a wonderful thing, and those of us who have lost it should not make fun of those who haven't. Apologies.

The sort of institutions that you are thinking of targetting will not hire freelancers they will go for major consultencies. Also they will buy or lease their own server farms.
