Hi, I know it's a bit late for a reply on this, but basically there is no way you can speed it up without using social points. If you have a lot of lifestyle points you can use the social point flower to get some sp.
I assume you didn't manage to finish it, but the event will come round again in the future so you will get a chance to complete it then, and the second time you may not need any sp as it is already part done.
In the meantime it is a good idea to gather some sp by doing social tasks so that if you do need a few, you already have them.
I didn't manage to complete this event either, I think it was very tight on what you needed and the number of constructor coins required seemed to be impossible to achieve with the amount of candles you could make.

Good luck for next time.
