For gum , just make sure you've got hot water, your 25 degree tip, and get close, hit it at an angle, and up it comes. Good selling point: Get the gum up before it has a chance to create a stain that will be a real PITA to get out.
There are many creative ways to market yourself. Be careful about offering rate reductions. Word could get out that you do that and people could start to expect it out of you, and hold out until you cave. It's pretty much a judgement call. I've said it many times: What works for one guy may not work for another.
Nice website. I can see one or two things that MAY be a problem, but here's the thing that jumped out at me: I clicked on the "about us" part at the homepage. In big letters at the top, it says, "If it's worth doing right, it's worth doing yourself". Good advice, but what does this say to the potential customer visiting your site? It says, "Don't hire me, you should do it yourself." Great format and design, but I'd remove that quote, and fast! Good luck.
