i know there is a website called playerup and there is a facebook group for sale. However, after a few times of buying the group on it, I found that they sell quite well...so if you are interested in which group they introduce in it, please research that group carefully and then buy it. on the other hand, a while ago on this bhw there was an article posted about trading activities with intermediaries in it for a long time so i recommend you to deal directly with the seller on it, that's how i do it and over 2 trading is not a problem at all. The last thing I want to tell you is that your team is quite unique so you should target an area first, then buy the group that you think is suitable from from renaming group, description, title,... because I bet there will be very few groups related to the topic you want to buy
