Predict which cars make and model will likely be bought by customers using R programming

I want to start a business of selling cars in Africa. I have different brands such as Toyota, Nissan, Honda. I need to know which cars the customers will probably buy.
1) I need help to build my dataset which the data I have.
2) Using the dataset, predict the brands and models that I should sell to make more profit.
I would like to use logistic regression, forward variable selection, backward variable selection, ridge
estimation, LASSO, and others as algorithms. I need someone who is good in R programming.
