How to Choose a Rod

[spiderman6]

Plz help me (and excuse me if i could not write clearly, english is not my first language):
I am a newbie. I did sunfish for the last couple of years with 15$ southbend walmart rods. this yr i have started doing carp (yes we eat carp) and need your suggestion. i drop my bait from a bridge (so i can see the area is clean of debris), use corn with braid 50lbs with a very basic abu garcia rod that i bought for 5$ from a thrift store. now today 3 big carp severed my line and ran away. i realized i made mistakes like didn't open the drag button on time (so line severed right away), did open drag button (so carp took all the line before i could control and tore the last knot to run away), i tried to stop the line at the last end (it tore the line again, may be reel was not holding enough braid). braid was becoming very fragile for some reason (but it was brand new). i decided i need to get into 'real' rods and things. So here is what i will be doing and i need:
a. will try catching carp (8--10 kg), sucker (2kg)
b. will drop bait from a river bridge using 1.5oz sinker and Mushtad curved size 2 hook
c. dont plan for other types of ishes, at least not for now

i need:
a. suggestion for a rod with complete accessories (rod, reel, line) for 10 kg carps
b. best source
c. not to be cheapo but would be nicer to remain economic

thanks in advance
