Getting into boxing/similar combat sport?

ey there im interested to develop some fighting ability but even more than that ive always been intrigued by boxing but never really had an opportunity before. how would i go around to getting into it, i have no experience what so ever, i did tae kwon do a while ago but nothing recently. im decently fit i guess, 5'8 70kg, i can bench 75kg and im alright with body building and weight lifting, ive started some cardio lately, just curious as to whether i need to know anything before hand, tips and guide would be appreciated
