Find someone with a passion for sorting data, control their tendency to over-complicate or seek detail, and you're on your way. However, you as principal of the company need to understand the system, even if you're not the one doing it. Also, if you hire someone else to do the basics for you, make sure that you have some checks and balances in place. See Owner's review for a checklist of ideas that you should consider if someone else is keeping the books. The basic building block to good books is data entered in the right place.
Bookkeeping is merely recording expenses and income.
Whoever is entering the data needs to understand the true nature of each and every expense, and be able to put it in its right place. To begin with, you need a system to identify each purchase, and note its account number, or at least identify the category. This can be done by you, going through bills and marking each one with the right account name or number. The electric bill is easy - utilities, 5820. The hardware store might need a bit more thought if you want to separate small tools from supplies - the drill you bought is 4809, the lumber you bought for packaging is 4550.
