SQL server Query help

I have four table like below:
CREATE TABLE Party               ( PartyID		 int identity(1,1)not null, PartyRegisteredDate datetime,   MemberNo varchar(16),  SubsNo varchar(9),  PerNo varchar(2)     )
CREATE TABLE Contract            ( ContractID	 int identity(1,1)not null, PartyID int, MemberNo varchar(16),  SubsNo varchar(9),  PerNo   varchar(2) ,   ContractStartDate datetime, ContractEndDate datetime)
CREATE TABLE IndividualContract  ( IndContractID int identity(1,1)not null, ContractID int,  PartyID int, MemberNo varchar(16), SubsNo varchar(9), PerNo varchar(2) ,ContractStartDate datetime, ContractEndDate datetime )
CREATE TABLE Customer            ( CustomerID	 int, IndContractID int, ContractID int,  MemberNo varchar(16), SubsNo varchar(9), PerNo varchar(2))
The business Key is MemberNo, SubsNo, PerNo in all the 4 tables.
Contract table has PartyID as foreignKey from Party table
IndividualContract table has ContractID,PartyID as foreignKeys from Party table and Contract table.
Customer table has IndContractID,ContractID as foreignKeys from IndividualContract table.
CustomerID in Customer table is nothing but PartyID.
IndividualContract and Customer tables should be one-one. 
--Below is the source data in #Source table
Create Table #Source (MemberNo varchar(16),  SubsNo varchar(9),  PerNo varchar(2),PartyRegisteredDate datetime, ContractStartDate datetime, ContractEndDate datetime) 
Insert into #Source

This source data should go to the above 4 tables.
But the requirement is:
1. For one MemberNo there should be only one row in Party table. So in my case ,the party table should have only 5 rows like below.
	PartyID	PartyRegisteredDate	MemberNo	SubsNo	PerNo
	1	1987-07-14 00:00:00.000	824212	091547708	01
	2	1993-01-01 00:00:00.000	864211	041609336	01
	3	1993-01-01 00:00:00.000	864212	113523275	01
	4	1993-04-05 00:00:00.000	867616	041609336	03
	5	2002-09-01 00:00:00.000	054911	079548709	01
2. The contract table should have only records with PerNo='01' for one MemberNo.So in my case this table should have like below.
	ContractID	PartyID	MemberNo	SubsNo	PerNo	ContractStartDate	ContractEndDate
	1	1	824212	091547708	01	1987-07-14 00:00:00.000	2010-09-01 00:00:00.000
	2	2	864211	041609336	01	1993-01-01 00:00:00.000	1999-12-31 00:00:00.000
	3	3	864212	113523275	01	1993-01-01 00:00:00.000	1999-12-31 00:00:00.000
	4	5	054911	079548709	01	2002-09-01 00:00:00.000	9999-12-31 00:00:00.000
3. The IndividualContract and Customer should have all the records from #Source table, as IndividualContract and Customer tables are one-one.
4. IndivuidialContract table should look like below:
   Here the ContractID is based on the SubsNo from Contract table.
	IndContractID	ContractID	PartyID	MemberNo	SubsNo	PerNo	ContractStartDate	ContractEndDate
	1	1	1	824212	091547708	01	1987-07-14 00:00:00.000	1988-09-30 00:00:00.000
	2	4	1	824212	079548709	02	2010-09-01 00:00:00.000	2010-09-01 00:00:00.000
	3	2	2	864211	041609336	01	1999-03-01 00:00:00.000	1999-03-01 00:00:00.000
	4	3	2	864211	113523275	02	1999-03-01 00:00:00.000	1999-12-31 00:00:00.000
	5	3	3	864212	113523275	01	1998-06-01 00:00:00.000	1999-12-31 00:00:00.000
	6	2	3	864212	041609336	02	1998-05-01 00:00:00.000	1998-05-31 00:00:00.000
	7	1	3	864212	091547708	03	1998-06-01 00:00:00.000	1998-06-01 00:00:00.000
	8	2	4	867616	041609336	03	1998-05-01 00:00:00.000	1998-05-01 00:00:00.000
	9	3	4	867616	113523275	03	1998-06-01 00:00:00.000	1999-12-31 00:00:00.000
	10	4	5	054911	079548709	01	2012-08-01 00:00:00.000	9999-12-31 00:00:00.000
5. Customer table should look like below:
   IndContractId and ContractID for this table comes from IndivuidialContract table.
	CustomerID	IndContractID	ContractID	MemberNo	SubsNo	PerNo
	1	1	1	824212	091547708	01
	1	2	4	824212	079548709	02
	2	3	2	864211	041609336	01
	2	4	3	864211	113523275	02
	3	5	3	864212	113523275	01
	3	6	2	864212	041609336	02
	3	7	1	864212	091547708	03
	4	8	2	867616	041609336	03
