Yes, it is possible to reconstruct the sentences. You're looking for a proof-reading, I assume?
Reema's answer is very spot on, here's my attempt (there's many ways to re-write this):
"I would like to know more about internet marketing. Could you please suggest some websites on the subject? Also, is there free registration on these sites?
Please send me some information regarding internet marketing, and related online jobs."
...and remember to say thankyou! ;) hehe
