Consult me for the best online marketing program

We primary a construction company in Boise Idaho. Our primary services right now are remodeling and drainage systems, which do not exactly flow together from an advertising standpoint because our customers want a specialist to either remodel or provide them with one of our specialized drainage systems. I have considered dividing the company into two, with two distinct names just for that reason. I don't want the hassle of all of that if I don't need it. Also I want to expand to other things and appear as a specialist in other arenas such as a painting specialist, or a maintenance specialist, or maybe even a mover. We are equipped and capable to do several different trades, but our local customer are very finicky about hiring a "jack of all trades, master of none" I am looking for marketing ideas to promote different services under one company umbrella and appear to be a specialist at any service we offer. I also want my entire marketing campaign online. I am seriously looking at V fliers websites and fliers because of the Craigslist component. I am open to suggestion if there are better way to do this and I am concerned with their SEO ability. I think this project would be a few hours of consult with myself, a few more hours of research on your part, then a unkown amount of time for the initial implementation of the decided plan. After that I would want some sort of ongoing hourly or project support until I have all the marketing in place that I need, which we will probably never achieve, so it could be a long term relationship.
