I'm really bad at receipt organization and data entry part of bookkeeping.

For instance, some accountants only provide tax and bookkeeping services, while others aim at being a "trusted advisor" to your business.

I've had issues conquering the least fun part of running businesses - bookkeeping and accounting. 

Payroll, bookkeeping, etc can mostly be done remotely.Here is a great list of questions to ask a potential accountant:http://www.biggerpockets.com/forums/51/topics/70447-questions-to-ask-a-cpaAlso check out the www.NAEA.org page in your search.

I found a few bookkeepers who also prepare taxes.

The only time I have to do general ledger double entry bookkeeping is for Security Deposits and Prepaid Rent -- but this is rare and I have the "how to" section marked in the missing manual. 

However, the cost such as plumbing, ductwork, electrical, and lumber have to be capitalized and added to the basis of your house unless you meet any of these: 1)  The total cost is less than 2500. ( not just plumbing or electrical- total ) De minimis safe harborThe safe harbor applies to amounts paid during the tax year to acquire or produce what the regs call a “unit of property” (UOP), you must meet these requirements: (1) at the beginning of the tax year, the taxpayer has written accounting procedures treating as an expense for non-tax purposes amounts paid for property costing less than a specified dollar amount (which will be 2500 for you), or with an economic useful life of 12 months or less;.(2) the taxpayer treats the amount paid for the property as an expense on its books and records in accordance with its accounting procedures. ( do this on your bookkeeping software or whatever you utilize)(3) the amount paid for the UOP doesn't exceed $2,500. as substantiated by invoiceNote: The cost for the Unit of Property includes l additional costs (for example, delivery fees, installation services, or similar costs) if these additional costs are included on the same invoice with the tangible property. 

So in short, I do log all my specific task from book keeping, phone calls, driving for dollars, closings, bank deposits etc. and even get to add tax audit this year. 

Could I split into 2 units one commercial and one residential for ease of bookkeeping?

I do my own bookkeeping.
