Good day,
I am an expert in elearning systems and development with over 15 years of experience.
Of course this is not a bid but a way to communicate with you as there are a lot of details that needs to be discussed.
For this project, you have WordPress, Moodle, OpenSIS & SugarCRM, to make the integrations, you need to know first of all that the base of WordPress, OpenSIS, & Moodle are free, but they are paid for further features. OpenSIS is free for the community edition, but not for the pro edition, while the OpenSIS-Moodle integrator cost $3000 from them without installing and configuration of it.
SugarCRM is a paid service and of course there are at least 3 levels of service.
So, the type of integration and implementations which includes all the four systems plus some additions to them is going to be a complex implementation, even though that the use needed is much simpler.
You have to expect that the whole system would cost you at least $10,000 for the first year, then it will be service charges.
If this is suitable for you and you want to continue, please contact me.
If you like to find other solutions that may be less costly, we can discuss a few things about it, I will need more details about your implementation needs to give advice.
Please be kind to initiate a discussion with me.
Best regards,
