(20M) Portfolio recommendations to create long term wealth (10-15 years) through investments in stocks

I've made a projection of how much money I will be making at my new job, and this following 8 months I will be able to save up to 2500 USD that I intend to invest in stocks and hold for at least 10 years. What stocks, index funds, ETF's, etc, do you recommend me to invest for the long term?
