Price of this custom item?

[Legendairy]

One in our group wants a custom item that's a flowery/viny vest that 3/day the vines grow to a reach of 10' and entangle as the spell. So I was thinking the spells would be plant growth and entangle. Would this be the right cost for the spells?

3(sp)x5(CL)x1800 for plant growth
And
1x1x1350 for entangle
And for 3/day
5 divided by 3= 1.6
For a total of 45,360.

If there is a more cost effective or my custom magic item math is off please let me know. As always, thank you playgrounders!!!

Just entangle is probably good enough, honestly, since it's less powerful than the spell, but doesn't require existing plants.

1*1*1800*(3/5)=1080gp.

Makes sense, thank you so much.
