 N.B. 

Русское быть уверенным в чем-либо передается в английском языке конструкциями с прилагательными sure и certain. I'm sure

(that) обозначает высокую степень уверенности, оставляя, однако, возможность того, что 

высказанное мнение может не подтвердиться, в отличие от I'm certain, которое выражает 

абсолютную уверенность в справедливости утверждения, основанную на реальном знании фактов и обстоятельств, возможно, неизвестных собеседнику. Такое же различие относится к наречиям 

surely и certainly:

I'm sure he didn't write it/Surely he didn't write it, he is not that sort of person

Не может быть/Я не думаю, чтобы он это написал, не такой он человек.

В большинстве случаев, "maybe" и "perhaps" имеют то же значение. Однако, в отдельных ситуациях будет неправильно использовать "maybe", поэтому если не знаете что именно сказать в конкретном случае, то лучше сказать "perhaps".

"maybe" звучит неофициально, так что его не используют в официальном контексте. Это более разговорный вариант, его можно услышать у носителей редко услышишь, но письменно можно встретить только "perhaps" . К примеру, в докладе я бы не написал "Maybe we shall only know the true cost of the project after it has finished". Правильно будет Perhaps we shall ...". Хотя в разговоре можно встретить и второй вариант.

Если в предложении уже есть слово "may", то неуместно будет добавить "maybe", только "perhaps".

Вкратце, проще сказать "perhaps", чтобы не путаться. Если же это не деловое письмо, то сожно использовать "maybe", но и здесь "perhaps" вполне подойдет.
