Review some of the freelance sites, see what the going price is for any of those tasks.
After you pic yourself up from the floor and recover from the shock, charge what you are worth, not what everyone else is charging.
Find what separates you from the rest, capitalize on that in your proposals. And one more clue: when you submit a proposal, don't waste space justifying your skills (that is what your portfolio is for.) Concentrate on the project, and how you would solve their problem best.
