Bring the 19th century charm back to my house

I have a house on Federal Hill, one of the most historic parts of Providence. It was built in the 1880s, but has new, white vinyl cladding, which is effective and durable but not very interesting. I want to know what my options are to add window and post moulding, and make the bay windows and front porch look nice. I'm not necessarily looking for anybody to do the actual work at this stage; I just need a designer who knows what products and techniques are available, to make the house fit the neighbourhood better.
