Definitely start with a CPA for the chart of accounts. Bookkeepers focus on working with a defined system, not on "defining" the system.
On a different note, you had mentioned that you had a great deal of historical data to input. Is this data from a previous accounting system? If so, I recommend using the same chart of accounts as the previous system and then make revisions to the chart of accounts and adjusting entries to the previous data. Otherwise, you will not be able to tie back to where you left off in the previous system. Even if you didn't have an accounting system previously, you will still need to tie back to your 2009 tax return if data goes back that far.
Also give consideration to the most efficient ways of getting that information into quickbooks. If no previous accounting system, you can import bank data from your online banking and then code the transactions to respective accounts after it is imported. Then, depending on how far the records go back, you will need to book transactions for payables and receivables at the end of each historical period that you want to get right on a GAAP basis.
