Ebook program

Ive written a hard-back book. Now i want to transfer the file into an ebook. Any suggestions? Software, websites,,etc..?

When one purchases resell rights for ebooks and softwares on line,does one have the right to give these materials free on the web?

I want to offer an ebook to my customer and it requires unique username and password to access it. I already have a list of unique combinations (username and password) generated from my ebook software and it is stored in a .csv file on my website. After order is processed successfully by any order processing system, I want to trigger a process.
Here is the total process:
– After the order is processed successfully, it will capture that customer’s data (like name, email, etc) from the order processing form or it can use any other method to capture customer’s data.
– It will retrieve the first unused combination of unique username and password from the .csv file.
– It will deliver the retrieved information (unique username and password) to that customer by generating a mail or a autoresponder.
– The whole process works automatically so that once it is up it will work again and again without my intervention for each of my new customers.

How do I code the total process?
I’ll not allow the customers to edit or delete the record or change the field information (user name) and (password), which is kept in .csv file – The reason is – it is a list of say 1000 unique combinations of username and password and that have already generated by a third party ebook software. The unique username and password is required by a unique user to access this ebook. Anyone or I are not permitted to change it. I just need to read the latest unused record from the file and send it by a mail to a new customer, who purchases my ebook.

For better performance, MySQL database can be used.

A cgi script made with perl can solve my purpose.
