If your committee is almost inactive then you, as an owner, can obtain your own quotes and submit them as a Motion to the General Meeting. You will also need to submit an Explanatory Note of not more than 300 words with each Motion.
Depending on your scheme’s Spending Limit you may need to obtain 2 quotes.
You will have a deadline in which to submit the Motions by to enable them to be placed on the Agenda of the next General Meeting. Check with your SM.
See Strata News #223 in the following link for how to write a Motion: https://www.lookupstrata.com.au/nsw-explanatory-notes-motion-on-an-agenda/
If that fails then get yourself on the committee ASAP.
