Any owner can self nominate for the EC, and do not need a second (unless by own strata plan specific by-laws).
If you are battling the developer /builder then you are probably not the only one and using the governance procedure provided by the EC could well support the problems you are having.
If there are significant problems, do not delay getting legal / experts advise ASAP. This begins with the EC and then includes the OC.
Do not be too concerned at the effect this will have on property prices, my experience has been that the impact has been positive on prices and time taken to sell.
