Hello,
First off, you can use Abe, this is a python block explorer that is the standard, all block explorers are tweaked Abe. You will need to tweak it to get what you need. I can not do that as I don't do python.
If you want a special software, written from scratch for your task, I can do that, with either C++, C# or Java, as you prefer.
This bid is for the first coin, each other coin I will charge $100 (You'll pay around $120) only, as the software will be in place and only needs adjustments for new block chain.
My advice would be to try to use Abe, it's good and proven.
Regards
Hawas
