I'm looking for a freelance data science trainer to get the training as most of the institutions are expensive, and they don't allow monthly instalments. I'm looking for a trainer who accepts the fees in monthly instalments because I'm an entry-level working professional and I can only afford to pay a part of the full fees from my monthly salary.
Hi, I will support based on your requirments.
