Need some ideas on how to implement my project to help my customers

I own a hood cleaning business - which is a specialty pressure washing firm. My husband and crew remove the food grease particles that build up inside a commercial kitchens, hood, ducts and exhaust fan.I'm watching many of my good customers really financially struggle with the latest economic downturn. I'd like to help them. I figure if I can help them figure out how to return their businesses to profitability and boost their sales, it will protect my business, since my business is dependent upon how busy my customers are at their restaurants. I have some keen small business mentoring / consulting skills which would really help them and I tutor owners in QuickBooks on the side as I get time. I used to teach college accounting and business management classes, and owned a tax practice that I shut down a few years ago when I grew tired of preparing tax returns. I've seen all the traps my accounting students fell into, and many that trip up small business owners. How you input the data into QuickBooks and other management databases makes a huge difference in your ability to peruse it to make management decisions or resolve issues that arise later on.I've gotten some feedback from my blog that JumpUp has given me here, and also my own blog that outlines tips and time-saving techniques I've come across in my teaching and business counseling experiences.http://a-quipmentrepairs.com/b... anxious to create an online training center where I take topics of interest from my blogs and turn them into step by step tutorials that new and struggling business owners can take at their leisure. I'd sincerely appreciate knowing which topics are of the highest interest to any readers here, so I can determine where to start. Time and money are both at a premium so I must focus my time on the topics that will generate the most readership.Here are my obstacles that I haven't been able to work around yet. And I'd love any ideas or suggestions you can come up with, even if you think they are lame.lack of believability - most people don't expect that a "greaser" would know anything about running a business office - but I do. In fact, I'm a heck of a lot better at tutoring than I am at hood cleaning. However, my husband is an absolute wiz at equipment repairs and hood cleaning. He runs the show in our business. I just kind of tag along. My clients think I am lying to them when I've offered to help them analyze their businesses and business offices for hidden costs and budget busters so not one has consented to let me work with them.How do I package / present this offer to help my customers? I'd like this project to become a value-added perk for my customers. I don't want to charge them for the tutorials bandwidth if at all possible. The ones who need this help the most are the ones least likely to be able to pay for it.marketing of my clients. I want to help boost my customers' sales. I'd like to put some kind of spotlights in for them at various points in my tutorials. Personally, I get extremely annoyed at marketing pop-ups when I'm visiting websites. How can I help get more people into my customer's restaurants as a part of the project without angering the owners who are studying the tutorials?Help??
