Deciding between managing our own account and having it managed

(Apologies in advance if I am not making sense or seem misinformed, this is a new financial venture for me and my fiancée.)

Title sums it up but here’s the details:

My partner and I have most of our funds in HYSAs and Retirement accounts, but have about $20k in an investment account. It’s a mix of stocks and ETFs, mostly large cap – but it hasn’t been performing well and we want to reset – as well as take the opportunity to write off a loss of about $1.7k.

We spoke to a CFP/Fiduciary yesterday and he ran a Morningstar report as well as sent us a proposal for passively managing our funds, but with tax loss harvesting and rebalancing. In the proposal it shows exactly what ETFs they would allocate our funds to and what percentages. They take 1.18% quarterly plus a $75 annual fee for managing the account.

Three questions:

Is this management fee average/normal for this fund amount?

Also, should I just take his proposal and use it as a guideline and just buy everything he proposed without having them actually manage anything? It’s a much broader diversified portfolio that we currently have that mostly consists of BlackRock ETFs.

At this fund amount does tax harvesting and rebalancing really do that much?

Thank you!
