Reccomend an IP Camera Install Company for Home

Hi All
not sure if correct forum

but can anyone reccomend a company in the sydney area to install IP cameras? I want hikvision cameras specifically

Ive gotten a quote of $3.5k for about 6 cameras (still pending the model numbers)

If you can reccomend one please let me know. more than happy to supply the camera myself or buy off them if reasonable

Thanks!
