We use
www.cleardocs.com for all vanilla entities and supplement with shareholders / stakeholders agreements (legal) if required. It takes no more than one hour to start all of these online and maybe another one hour for ABN, GST, TFN registration.
We use to operate like other firms and charge around $1500 for these without ABN, TFN rego (and we used a law firm to incorporate) but we much rather the clients spend the monies on more valuable advisory fees with us - which they often do. There is nothing complex about standard entity establishment (but the advice on entity structure is a different story)
Total costs are;
$537.50 for Company Incorporation (including the ASIC fee) Including GST
$137.50 for establishment of discretionary / family trust Inc GST
$440 Inc GST our fee to complete process.
$200 Stamp Duty to Victorian State Rev Office for trust deed
Total $ 1,315 Inc GST
You could easily spend another $500 to $1000 on structural or consulting advice with us but at least you get value for it. There is no value in paying $2500 for entity establishment alone.
So depending on what they are including in the $2500 it may or may not be a suitable fee.
