You don't need a partner
Get a part time book keeper then...
You need someone to bake for you. There are plenty of chef's who need extra income and can work afternoons before they start their main job... until you need them full time.
Expect to pay them $20-25/hour (ok ones) so look at your cashflow.
If you want someone cheaper - advertise in the local tafe's but you'll need to do quality control more diligently. You might find someone for $15/hour.
It takes a lot of looking to find someone with your needed skills and a personality match... don't forget you have to work with them
Took me 7 chefs and 8 months to find one without an ego and who followed directions... he's awesome and you can't have him
Your profit is in marketing yourself and expanding your sales but no-one can show the passion that you have for what your doing
There are places that hire out commercial kitchens on an hourly basis (don't forget prep and clean time in your figures
)
If you have any specific questions, I'm more than happy to help.
Cheers,
Ross.
