I just want to throw out there that if you want to stay below a certain pray level(most ppl prefer below 31 pray zerkers) that you should also add this into the details . I just recently had 3 zerkers made doing what you did and one guy went against my terms of going above 31 pray. (So i got it for free pretty much). But the main quests people do if they follow a guide from searching zerkers will show a quest guide which leads you past lvl 31 pray. Sorry if you think this is spam just trying to help you out as I've came into the problem in my pass.
Edit: Along with that @Yeti is awesome person who is very fast at what he does that wont cost you a arm and a leg.
