I am wondering if you are designing HYIP scripts. In this case it would be h-script.
The script is built upon smarty.
Demo and some information about the script here: [url removed, login to view]
Designed h-script here: [url removed, login to view]
My requirements would be similiar to arriels. Clean and modern design and most important live statistics about deposits/withdrawals and account earnings (so earnings are updated instantly without refreshing the page).
If you have any questions feel free to contact me!
