Refining the component for Jumla (passing tests with the output of certificates)

Got it:
1. Site operated by Jumla 3.4. The site will be tested (in terms of component developers). After passing the test, the participant must be issued a certificate with a certain set of information.
2. Components for passing tests and Russification to them:
- iJoomla Guru PRO v4.0.6
Joomla Quiz Deluxe v3.3.2
These components have approximately the same functionality. In terms of use, both can be used for tests. Quiz Deluxe is easier to work with, it is preferable to work with it, there the basis for the correct formation of the certificate is already laid. But I can leave this issue to the discretion of who will finalize the component, if there is experience in refining iguru, this option is also discussed.

What needs to be done:
To finalize the conclusion of the certificate, which is issued to the participant after passing the test.
The certificate must include the data of the participant, and this data must be entered by the user himself before the test. The data should not be correlated with the registration of the participant on the site. I mean. A person must first enter his or her data with his or her hands, pass the test and receive a certificate with the data he or she entered plus the test results.
In particular, Quiz Deluxe should be:
1. Make sure that the fields with information for the certificate can be filled by the user regardless of registration on the site. Set up the information input fields. Preview the certificate, save the certificate to the user’s computer and send the certificate by mail.

2. Put on the certificate the inscription that is formed in (Install Feedback Options - 4th in a row - Quiz Feedback Options (bottom) "If user passes, display:".
Response of the component developers to the revision:
1. The workload is 4 hours.
You need customization with custom fields.
You need to make custom fields, and add their processing to the certificate.
ajaxaction.php and printcert.php files in FE/models/
- correct js in FE/views/quiz/tmpl/
- add field output
add preservation
Add download and printout to the certificate

2. Workload is 2 hours.
Pull data from the database depending on the result and output
Printcert.php in FE/models/.
Plus 1 hour for testing and revision.

For the cost of the work, I have an offer from the developers of the component. But they have a problem with accepting payments in rubles and are expensive.
At the cost, offer your price.

I'll send you a file with more details.
