There is a short window for commissions available. I have found a nice little place that is happy to sell me perticoating fabrics at a more reasonable price than $5-6 per meter like lincraft or spotlight making it far more reasonable to the customer.

I charge material cost upfront, and then 30% of that on top for labour. Understand that it takes time for anything to be made and it's a very reasonable fee.
Shipping is what ever the australia post quotes from my postcode to yours and I use their website to calculate that and happy for the customer to check also.

I have already had 2 orders and found them fun ^_^
