What you are referring to is proper "parquetry" and the labour is generally costly as it requires more attention to detail and is more time consuming... you may be able to manage cost depending on your choice of timber (note parquetry now also comes in engineered timber which can be a bit less) but the labour will be costly regardless... my google search of "parquetry flooring Sydney" came up with a few results so hopefully you can find someone there after a few enquiries... good luck! :)

Me too. I think you would not get a close enough match to your floor and then it would stand out. Looks good as you have done it

The knots look like pine to me. Is that raw timber or does it have a coating? A trip with the pic to the timber shop would be a good bet.
