Unfortunately there is no easy way. You just have to go in your country page:
http://www.buzzerbeater.com/country/53/overview.aspx and select another country and then the highest division. Once there you can check the s36 teams against the s35 ones and hopefully you will find the 4 who promoted. Alternatively check the champions of each the D2s. Do this for 4 or 5 leagues and you will have a good enough sample. Hopefully you will find teams with medium size arenas that can be of help.
LA-Bernspin is a good example for you though as he just promoted this season and his arena is not much larger than yours:
http://www.buzzerbeater.com/team/65708/arena.aspxHe maxed out all the sections
Another thing you could do is to fire your PR manager now and then rehire a new one in 3 weeks before the next price change takes effect. I think at your current prices you're going to sell out irrespective of PR. If you fire him before Monday you will not pay the severance fee and his salary but only his severance fee.
