Using a Data look up and redirecting to Unique PURLID?

In E9 I used an entry page with one input field (MemberID) with the form processing step (Create Hypersite and redirect to PURL) with a data look up, which went to a success page or fail page based on the data lookup. How do i accomplish this in E10?

Example - MemberID = 5485474 and PURLID = JaneDoel88bm5

Entry landing page with input for entering MemberID 

1. Enter MemberID (5485474)
2. Do a look up based on MemberID entered and if MemberID  exist, populate thier PURLID (JaneDoel88bm5) in the Landing page (www.sitename.com/vanityURL/PURLID) and redirect to that unique PURL (www.sitename.com/vanityURL/JaneDoel88bm5)
