1991 Dodge Stealth Timing belt removal

I have worked on cars for years and have a fairly good amount of ability. My question is having done timing belts in hondas, chains in GMs and several other vehicles is this a job I can do on my own with the 3.0 dohc stealth or should I pay a shop top do the work? I have all the parts I need. The issue is that the belt looks fuine but is lose. (Bad tensioner) So the whole thing needs done.
