Great advice. I'd only add that the OP seems like he's from a foreign country and doesn't have English fluency.

When you can't speak English fluently your shop's greatest strength will be technical prowess. Soft skills take a backseat until OP learns English fluently.

Of course this assumes that the OP wants to build a consulting business in an English speaking country. Maybe he/she wants to consult e.g. in France for French companies, but still posted on HM because advice from HN would still be helpful and relevant.
