Mac project/task manager with "price" column for freelance illustrator?

I’m searching software to keep track of my illustration projects and their prices (flat rate). It should cost less than 100 $.

I would like to have my projects listed somehow like this:
>>
Client X
– topic 1, n. illustrations, deadline, price, tax, to do
– topic 2, n. illustrations, deadline, price, tax, to be invoiced

Client Z
– topic, n. illustrations, deadline, price, tax, invoiced
<<

Yes, it’s a to do list but with cost -column.
I would like to see easily what projects i have to do, have to invoice, have invoiced and what have been paid already. And to see on one view the sum of all prices (todo: 20$, to invoice, 2345$, … and total). And also organize data like in the excample above, by clients, to edit easily.

I have checked out lots of “getting things done” apps, task managers, finance apps, database apps etc. but many of them lack some of my features or are too complicated or pricey. Closest so far seems to be Bento where i can make smart folders for any searches (clients, todos, invoiced…) but it’s just a little bit complicated and i have a feeling it’s not meant for my kind of use.

I have omni outliner pro and have been using iKGTD but it’s not anymore supported in Leopard.

Do you know an application that meets my needs?

Any pie chart possibilities (yearly rewiev of works done to different clients), ical syncing (deadlines), address book syncing (client database), etc would be great, but not necessary. Do not need time tracking. Webapps are ok too.
