Charging HST for self-employed people. In my case, it's not possible to charge HST. Any advice is much appreciated.

Hi, I work and provide food delivery services as an "Independent Contractor" to "Skip the Dishes" and make around $1000 per week and receive the money in my bank account weekly. 

It seems that I will make over 30K this year and I know that as a self-employed, I am required to charge HST if I hit $30,000 but the issue is this company does not provide a way to charge them HST. 

They pay delivery fee + tips for every trips and they direct deposit the money weekly. Can you please tell me what are my options in this case? And what happens if I make over $30,000? Any help is much appreciated.
