I would suggest that you take a look a the following link:
Cisco Networking Academy
Whilst this is for Cisco training I do feel that as biased as they are in some respects that the quality of training is superb. The CCNA is the entry level qualification but dont be complacent, to go from nothing to CCNA is a massive step!
I would also steer you away from TestKings and all these cram style study methods. They are useless in the real world. I have come across many a CCNP who has clearly got those 4 letters using these products and they know nothing!!
