Im starting an a small design business of my own- an online graphic design studio. The business will be completely internet based. I will be putting up my business website in a .com domain. The website will also include the following features:

1) SSL secured transactions for online payments by clients
2) "Request a quote" form for clients
3) Provision for transferring final designs to the clients by FTP
4) Company’s design portfolio in flash format

I am a newbie and have no idea which features to look out for in a host to make sure that i am able to build and run such a website.

To give a rough idea i want a website similar to this one-http://www.eharrington.com/index.html

Please suggest a good web hosting company that will suit my requirements.I am not looking for free hosting. Quality and efficiency are the important factors. Thanks in advance.
