Producer is only offering $300 for entire kit

I posted a few days ago about a kit rate negotiation I’m having with a commercial producer.

Today the producer came back and said they can do $300 and “that’s double what I have ever paid an AC”.

But that would be $300 for:

Nucleus M Kit Teradek Bolt 6 TX Teradek Bolt 6 RX SmallHD Indie 7 w/Bolt 6 RX (for me) SmallHD Indie 7 w/Bolt 6 RX (for Director) Atomos Sumo 19 SE (for client) Accsoon TX (for HMU and Production design. Both have actually been using it a lot and really like it) iPad (I include it in case someone wants a bigger screen than their phone) I also include 4 V mounts and a charger + all tapes, arms, cables for free.

Should I try to negotiate higher?
