Predict which cars make and model will likely be bought by customers using R programming -- 2

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.
