We're hoping to move to Australia asap

I've just finished my uni degree in social work.
My mum is a Australian Citizen.
My partner has just started a design business (no formal qualifications though).
We have a 1 year old son.
Whats the best sort of visa we can hope to get?!
There's hundreds out there.. but it's all complicated! We thought about her mum sponsoring - but can she sponsor us as a family or just me?!
Working holiday visa for my partner? skilled visa for me?
Thanks In Advance!
