Welcome to The Answerbank, Oakdaddy22.
However this site is based in the UK, where our 'petrol' (= your 'gas') currently has an average price equivalent to $7.41 per US gallon. i.e. it's about twice as expensive as in the USA.
Similarly, the Federal Minimum Wage in your country is currently $7.25 per hour, whereas the National Living Wage here is currently the equivalent of $11.49 per hour (and set to rise to the equivalent of $12.60 per hour next April).
So our reference points will be VERY different to yours.
However I did come across this thread from 8 years ago, where people in the UK seemed to be suggesting a figure of around £250 per day (+ 20% tax = £300 in total) for a mobile log-splitting service:

At the current exchange rate, that's the equivalent of $363 per day. Factoring in inflation would take that to around $460 per day now.
I hope that might help you but, for a more accurate assessment, it might be best to post on a US-based Q&A website, such as Quora.
