I don't know what the value of goalies is in your league but there are a lot of top goaltending prospects still available and if the limit for farm team eligibility in your league is really 30-games then you'll want to load up on goalies since they are the players most likely to remain farm eligible until they are ready to compete.
Off the top of my head the best goalie prospects available in no order:
Jake Allen (yes that Jake Allen)
Most, if not all of these guys are the top goaltending prospect on their respective teams and because of that they all would have a lot of value if things break right. At no other position can a prospect gain more value than at goaltender because simply getting a starting job is worth a ton.
