i want to insert new record in custom object guest_master__c name & email in lwc
in lwc want input text name & email, on clicking button save, want to insert that data into custom object Guest_master__C as new record.
 

we want the ability to send a quote to a lead in salesforce, only if the lead agrees to the quote/proposal and  willing to pay  then we would like to convert the lead to account and opportunity. 
Since Quotes are only available on opportunties, Sales reps are converting the leads into Accounts/contact and opportunity and if they dont make a purchase the deal is lost. that is leading to unnecessary records in salesforce , leading to duplicate records.
Any help is appreciated!
