Accepting payments for posts to Jobs & Experts

Hi, We are investigating using Jobs & Experts for a community forum for people looking for work and people looking for people to do work. We'd like to monetise the process so people can post jobs and find experts but whatever the fee is agreed to between the parties is paid through us to collect a commission. Can you please advise if this is doable natively to the plugin (appears not to be) or with another plugin or does this require custom development? Thanks.
