Display only "Courses" on external website

Hello Support, I inquire about above stuff and asked some freelancer coder to do it. They informed I can achieve this using multisite? is that possible? I want something like this mysite.com : central location with WPLMS script/database when instructor and student can login take course etc. category1.com/catergory1.php : Display course from category 1 category2.com/catergory2.php: Display course from category 1 also if possible category1.com have a search function etc so it can grab result from mysite.com All website are residing on the same server so i think I can use the same database to connect the wpllms??? anyway since you are developer of wplms if you have any ideas let me know even if this is achievable before I spend money hiring coder or something like this you will be able to do and I can pay you!!!
