If you have a Joomla 2.5 site and need it upgraded/migrated to a Joomla 3.x site, Passive Ninja can help. We can point you in the right direction when it comes to tools and potential issues. We can also do the migration for you. Use the contact form to get in touch. Your site will eventually fail you if you don't keep it updated.
Looking these services up online, I found Sarah Hayes in England charging well over $1000 for the migration. I found another firm, probably in India, charging $300. It's not free. Passive Ninja can beat the prices just mentioned on most sites. However, if your site has been around the block a few times, maybe it's better to build new and just migrate content. Content migration is only $100 extra on any brand new Joomla site we build, so it pretty much comes along free.
