Congratulations or maybe commiserations on being elected President, it is always reassuring to hear that the old fashioned Spanish attitude of doing as little as possible can be challenged correctly.
There is nothing to stop a resident getting a quote for any project but this needs to be supplied to the Administrator who along with the current President are entitled to make any final decisions based quite correctly on a number of competitive quotes bearing in mind, the cheapest may not always be the best.
The Administrator may well have a preference, but not necessarily be for the correct reasons though you are expected to listen to their advice.
As President though you carry the final decision and hopefully you would carry enough support if ever questioned, but be prepared to be shot down in flames IF things do go wrong.
Damned if you do, damned if you dont, comes to mind.
