Fixing some bugs and want to create backend sales filter for admin

Hi, I am looking for a professional WordPress/WooCommerce developer for bug fixing and want to generate a sales filter on the backend so that I can filter my sales according to the GSTs and want to generate an excel sheet of Monthly / yearly. It's a small Hotel room booking website, currently, if any customer booking a room for more than 2 persons then it is booked with an invoice of booking one room. I want that if someone booking for more than 2 persons then it should be booked 2 rooms and invoice should be generated according to the 2 room booking. For example, if someone books a room for 3 people then we allow rooms for only 2 people then it should be booked 2 rooms. Similarly, if someone booked a room for 7 people then rooms should be booked for 4, and so on. And I apply the PayUMoeny payment gateway on the backend but it is not visible on the checkout page need to fix this also.
