[Typo3] Fast Learner New to Typo, I want to setup a Print Shop

[David Matthews]

Hi I am researching CMS for my new business which is a Print Shop that 
does Flyers, Pluggers, Stickers, and Tees. I have searched and found 
some of my answers, I am moving from Mambo so I dont think it will be 
that hard of a migration, but what I need is the ability to work with my 
merchant account authorize.net as well as the ability to upload files. 
The order process would go something along the lines of... select item/ 
qty/size/ then upload necessary files then enter credit card info, then 
email confirmation. Is this possible? If so which script would you 
suggest, any tips to help with this project would be helpful, I am in 
the planning stages for the site
