Can you list all the countries in Africa that speak Swahili? Are there different dialects? What are the differences?

There are about 10 people that will be traveling to Tanzania several times and we all want to learn to speak swahili, we are all adults. We are looking for someone to teach us one day a week. We are in the Tulsa, Oklahoma area. Please reply to this with a way to contact if you can help! Thank You!

How do you say these words/phrases in kiswahili:
'love' (the idea - ie NOT I love, NOT he loves, etc.)
'Unity through education'
'World Peace through education'
'Opportunity'

if you know any african phrases (english or swahili) similar to these topics, that would be great as well. please no online dictionary translations.

best answer will be awarded
