Three Months in South America - Group Travel

I will be in Bolivia & Brazil visiting friends the first month, but I'm looking for travel partners from the first week of Feb- end of March. Here's a preview of what I'm thinking.

-Carnival arriving on Feb 6-7th and staying in a rented apartment in the Copacabana area. I plan to depart 13-15th.
-Iguazu Falls for a day or two.
-Buenos Aires: arriving Feb 16-17th and staying in the city for about one week (Ultra is on the 23rd, electronic music)
-Mendoza for some wine tours via bicycles.
Then a few days on the road north (some long bus trips) to get up near the Atacama desert (might exclude/pass through Salta before crossing the Bolivian border) but heading towards the Salar de Uyuni.
-Salar de Uyuni for a few days. It should be around March 1st by now.
-World's Most Dangerous Road (mountain biking, not for the faint of hear). departs near La Paz around March 5th-6th
-Cross Lake Titicaca
-Beginning March 11 I will be volunteering near Cusco with a local organization that provides water filters. Ending March 24th.
- March 25ish hiking Machu Picchu for 4 days with a few days in Cusco to celebrate the hard hike.
Leaving to go back to US on April 2nd.
