I have a small job for you, if you wish so.
I am ready to distribute a Lotus Notes database on a trial basis.
This means that it must be with an expiry date, 3 months after opening it.
Upon user's request, I will e-mail to the users the database.
When they open it the first time, they have 3 months to use it, after it will close.
There is no need to "re-activate" the database upon buying. They simply have 3 months to try it. After that, it is over. It is really for them to try. If they are happy to buy, they simply send it back to me, and as I will have designer access, I simply delete the script and install it on my server.
So it is a small job - if you are interested, you can let me know your price.
