Hi, I would be interested in this. I actually created a Vesk Mercenary Soldier for another PbP game on a different site that never took off. It's close to your pregen one but if it's OK I'd like to use mine since I spent a while creating it and would like to give it a whirl.
If that works let me know if you want me to post it here or via a PM.
If there ends up being an opening I'd be interested. I'm new to Pathfinder and Paizo's site but have plenty of experience with D&D and PBP. I would love to join this adventure. I have no problems with the requirements you have outlined.
