I'll probably be totally wrong on this (don't worry, some good help will come along shortly
) but I think you can use either:
Te quiero presentar.
or
Quiero presentarte.
If I'm getting any of this conjugation stuff right, I think you only ever conjugate the first verb, then leave the following one in the infinitive form. When using a reflexive verb with two verbs, you can either put the pronoun object first, or add it to the end of the second (infinitive form) verb.
Again, I could be totally wrong.
Edit: Oh, and I nearly forgot. Welcome!
