I've bought Odoo online and have just started to use it. I dont know how to find the version, but whatever is available for online use.

I sell different services, and can potentially (and preferably) sell multiple services on the same sales order. Eg I have fixed-price products (eg books), services that I would like to invoice on milestones (eg different kinds of trainings) and another set of services that I'd like to sell on time-spent (eg consultancy hours)

My quotations will typically have a book (different prices for different books let's say B1 - B10), and trainings (assume T1 - T10, each priced differently) and consultancy hours (also potentially different types C1 - C5, each priced differently).

Each of the books has a task assigned to it (B1 needs TaskB1 executed, B2 needs TaskB2 and so on). Similarly, each training (TR) has a set of Tasks that need execution, eg TR1 needs TaskTR1_1 to TaskTR1_5 executed; TR2 needs TaskTR2_1 to TaskTR2_8 and so on, ie each Training has a set of tasks and different trainings have a different number of tasks. And finally same goes for Consultancy, ie just like Training, each Consultancy needs a set of tasks to be executed.

Now my quotation typically has a book, a training and potentially a set of consultancy hours. When the quotation is accepted by the customer, I'd like: 

1. The sales order to generate a project

2. And depending on which book, training and consultancy was on that sales order, respective tasks be generated *within* that new project. 

Eg if sales order S001 had book 1, Training3 and Consultancy2, I want a project and tasks generated as follows:

Project_S001

--Book1Task1

--Training3Task1

--Training3Task2

--Training3Task3

--Training3Task4

--Training3Task5

--Consultancy2Task1

Is that possible? How do I do it?
