I could handle the hosting, so long as you do not mind PBEM and do not expect to be able to play several turns a day (I can usually run a turn in late morning or early afternoon GMT, some days in the afternoon, and in the evenings everyday).

Creating a specific map does not really require to have a third party host though: if you want the capitals to be known to all players, it only requires a public .map file made for this game. If you would prefer to keep the location of the capitals a secret, you would need someone to set up the game for you (and you would not get to see the .map file).
