All your credentials sound really good but in the end, I decided to pick seraphic_dream since her style of writing is closest to mine(me thinks). I'm also considering an English consultant but I haven't gotten any reply from her yet.

creatatrixa, cogs_and_gearrs, rika_cain and just_a_fangirl. Thank you, thank you so much for responding to my request. Guys, I'm really thankful for all your offers. It made me realize that fans from the Hetalia fandom are really supportive.

The first chapter is now in the works, and hopefully can be released within this month.
