I guess you're training right now? Just try to be in decent shape before going there. Takes some time to adapt to running and training twice a day 6 days a week. Depending on the gym/trainer you can probably get a fight in 1 month. In 2 months yes, i think you would be "in shape" for a fight. Generally it's hard to match foreigners with an opponent of same skill level since they don't know anything about you... Maybe you'll get an out of shape thai or another foreigner with very little experience.
