Spec Homes Or remodeling?

I know this is a real estate investing forum which I have read alot here and contributed some over time. I had a different screen name which I cant remember so I had to start a new one … Anyways… I am looking to expand from fixing up properties into doing spec homes , or custom homes , remodel etc… Anyone have suggestions on how to market these? I will be doing stick built and modular homes in the pa area. I am setup with 2 online lead resources but just curious if anyone is doing what im about to get into and what marketing they have done that gave results… Thanx for any info. I had a few rentals and fixed up a few foreclosures. I think it would be nice to have some work that I get paid for once its done instead of advertising like crazy trying to get it to sell.
