Bookkeeper For Tax Return Prep

Looking to build a long term relationship with an expert bookkeeper. Working on taxes for my U.S. based LLC and I have 500 transactions that I’d like help with categorizing. I need this so that I can fill out a P&L for the business. I use WaveApps so it should be fairly straightforward. I know that you will need my help with some of the transactions, but it would be fantastic to have everything categorized and then flag the ones that need my input. My business doesn’t have a ton of transactions throughout the year, but I would love to have someone that can help as needed and especially for taxes. Please answer the following: 1. What experience do you have with bookkeeping? 2. How much would you charge for this? Or what rate and how many hours do you expect? 3. When can you get started? Thank you!
