I second this.
I'd urge the op to do his own brute-forcing. This tool worked wonders for me in the past: https://github.com/gurnec/btcrecover
I can't imagine it taking long to brute force a password that only consists of 6 numbers... I wouldn't risk getting scammed by using an external service.
a 6 "number" password should be very easy! there's no need for OP to actually use any third-party service, i have never used https://github.com/gurnec/btcrecover but i've heard it's good.
"Jd8!O_" for example taked around 14 Hrs to crack with a I5-6600K ( i might be wrong tho ), if you use your GPU it should be even faster (depending on your GPu that is hehe
