Bitcoin Tax Report

I'm looking for someone that can help me create a tax report for my crypto, from 2017 until now. I've linked my platforms up with Koinly, and there is about 500 transactions - but Koinly seems like a mess and i don't know if this amount is true or not. I've used both Coinbase, Binance and Bitfinex for my crypto investments and trades. The tax report has to apply by danish tax law - and has to be done by the FIFO-principle. If this seems like a job for you or you have any questions, please let me know - thank you.
