I have used these mobile booking companies before but by far prefer Luxit as they are the most professional and reliable. Prices are good for the level of service you get. I also use them in Melbourne once and they were great there too.
I've booked hair and makeup for my mum for Mother's Day so looking forward to introducing Luxit to her. I know she will enjoy it :-)
Definately recommend if you are looking for quality and reliability.

Approximate cost: $150

We live in the lower North Shore of Sydney and have had both our front and back yard treated by tick safe. It's kept the area tick free so we haven't had any issues. Highly recommend these guys. They know what they are doing and are very easy to work with. Price is good too.
