As I said, you're not going to find anyone here who will do your work for you. It's a pretty straight forward approach, however:
1) Build a table to house your hotels. You'd need fields such as HotelName, HotelAddress, etc etc.
2) Build a table to house your clients. You'd need fields such as FirstName, LastName, Phone etc etc
3) Build a table to "join" those two tables (since a client could stay in more than one hotel). This table would include the Primary Key values from tblHotel and tblClient, and would also include the Date, LengthOfStay, PricePaid etc
Now when a Client stays at a Hotel, you would add a new record to the last table, where you would "relate" the records from tblHotel to tblClient.
