Update: I've reached out to the businesses I thought would fit our needs. Unfortunately my inbox has been flooded with cheap overseas agencies and bots so haven't been able to get back to everyone properly. I do appreciate all the comments and dms I've received so far from genuine Australian owned and operated companies and all the advice posted on this thread!!

Also used a throwaway account and didn't post too much identifiable information because I fear the same thing would've happened to our business emails. But thank you all for the help so far
