I wouldn't spend too much time learning accounting. Because it's not something that can be learned quickly. There are a lot of angles to accounting, like cash vs accrual accounting, tax vs financial accounting, etc. What I would do is hire an accountant who works with businesses of your size. Then ask him/her to walk you though one month of your activities and how they impact the basic financial statements: cash flow statement, income statement and balance sheet. Tell him/her you want to understand how to read financials, but don't need to understand how they are prepared step by step.
If the accountant is smart enough to understand what you are asking, then he/she will explain things to you and going forward you may be able to do that yourself.
I want to add that you may want to understand financial statements and financial analysis, not necessarily accounting. Financial analysis will tell you what's happening with your business, while accounting is debits and credits and that's a process to get to the end result, which is financial statements:
Accounting >> Financial Statements >> Analysis of Financial Statements
You may need to know step 2 and 3 above, but don't necessarily have to know step 1 in detail.
Also, just FYI, most probably you will have financial statements on a cash basis, unless you are a large company.
Finally, there is a lot of material online about accounting and financial analysis. And it's free. Just google :)
