Jeantee I'm not sure if completed novel can get a contract, and sadly even if you get contracted, you won't be able to get the MGS system which is to get paid $200 monthly by releasing 1 chapter per day with minimum of 1500 words for 4 months. The only way you can monetize your completed novel are by getting gifts from the readers after your novel has been signed by the editor and going premium and locked the chapters of your completed novel.
I'm not sure if your novel will be put in trending/potential starlet because your novel is completed. Without those two promotion, you will hardly get a new readers. So the only way to get new readers is by promoting your novel on your own.
