\opening{Dear Sir}

I am writing this inquiry in hopes that we can establish a relationship
that will be of benefit to your beautiful country and to our guests, who
would enjoy staying in such beautiful surroundings. While on a visit to
your neighboring country, Mandika, I had the opportunity to spend
several days in your country. I inquired about tourist facilities and
discovered that they were yet undeveloped. Naturally, I thought that
your country could certainly benefit from the popularity that its beauty
would create among potential tourists and the income that they would bring.

Abenteuer Urlaub has established several holiday resorts in Africa
with great benefit to the host countries in terms of job creation
and revenue generation. There is great potential in both of these areas
for a country with such natural beauty as yours. I would thus
appreciate the opportunity to present our concept to your ministry in
hopes that we can establish a mutually beneficial business relationship.

I look forward to hearing from you and having the possibility of
presenting our ideas.

\closing{Yours Faithfully,}
