Build a Website for Bookkeeping with online payment getaway

Hello, I am looking to create a bookkeeping service online. The options that we need: • Username and password generator for clients, I want them to be able to log into site and have a profile where they can view invoices that they've paid, where they can upload files for me to do their work.. etc. • An eCommerce store of some sort where my clients are able to purchase my services, as well as some products - like budgeting spreadsheets, and literature that i've published. Lets say someone doesn't want to buy into a monthly contract with me.. they will have the option to do it themselves with my guidance. I even want to outline packages someone can build a custom package. I'd like to be able to take credit card and debit - so i'll look into TD Merchant services, i've used them before and I think they're pretty good! I will call and see about linking them with a website. • A blog page where I am able to go on a few times a month and update a blog with new information about the 'industry', advancing software packages, info about tax time, etc. • I was hoping to have an interactive calendar also put somewhere on the site - this can let people know when tax time is coming, when due dates are, etc. I was also hoping to have a calendar for each client that i have signed up with me 'monthly' so that I can put in notifications for them - like then they're HST is due, or when they need to pay their source deductions by. When they need to have their info in to me to be able to complete their file on time. • Last but not least a pretty website. :) One that reflects me and my elegance haha (jk, but something modern, functional and easy to use for even the beginner computer users)
