LOMO sends all their films to their LOMOLab in Taiwan, so turn over is extremely long (14-18 days) so be prepared to wait!
If you want to do more E-6, you could try it at home but you'd need more eq. than B&W, PM me i can send you the list.
Best alternative would be to send it overseas, which is what i do sometimes for films i do not want to mess up, and then mount it onto holders myself at home.
DIY, not too expensive. Hong kong has great labs, but so far, my US development's scanning is the best. Colours are true to it's nature.
