House Makeover

I am on a very tight budget and have to do most of the work myself. I am looking for painting ideas for my home. It was a street car station in the early 40's and converted into a home in the early 50's. It has the original windows, siding. The house is brick. The back is shaped like a half moon because the street car tracks were along the back of the station. The brick was painted in the back red and probably needs painted again. The front is the original brick - not painted. The top part is siding. I am looking to possibly change the color of the siding/awings/porch floor and the cement walk outside the dwelling. Also, help with entry door color. Any help would be greatly appreciated and unfortunately, I am very bad with colors. Thank you so much
