Help- boat trips along the amazon

I've been looking at boat trips along the amazon and was wondering if anyone could recommend a company as everything I've seen has been in the region of £1,000! I'm looking to travel from Peru to Brazil and wanted to know prices and time scales. Any help would be much appreicated!! Thanks

Hey there,
I posted this on this forum a while ago:

The last time I was there got a pretty good deal with a travel agency called Equipol, it was recommended by Hotel Tropical Manaus staff, where we stayed, but unfortunately their website is in Portuguese, only:
http://www.equipoltur.com.br/pacotes.htm

Here are some other options in English:
http://www.amazonastravel.com.br/river_cruises.html
http://www.amazonriders.com/
http://www.captpeacock.com/
http://www.ciaecoturismo.com.br/
http://www.kaui.com.br/main.asp?language=EN

Wish you a nice trip!

Cheers,

Bruno
