Cool down mate!
I will offer real services, real work and results!
I do have a plan already made what and how to do things.
It will contain some blackhatplugins like likelocks but thats only good for businesses.
The faked visitors will only help me to get the full amount every month.
I offer at least 100 visitors per month to the business' site. If some serverissues will come up or any other things happen and the page will only get, lets say 65 visitors in one month. I have to give them the upcoming months for FREE. To save that, I will buy visitors. In fact there are not at least 100 visits/month.
I apologise for being so harsh initially. It seems your ideas are still BAD, but not as bad as I initially thought with your OP. In the OP it still looks like you are not wanting to do work, but instead send fake visitors.
Since you have clarified, it now makes a little more sense - you are actually intending on doing some work.
However, you are still going about it the wrong way. Firstly, you are wanting to send them fake visitors - that's wrong, no matter if it is 100 or 50 or 20 fakies per month. The point is, you are deceiving them.
I think the real problem is in your offer. How can you possibly guarantee the # of visitors? We know that you can't *guarantee* a rank on Google, so if you can't do that - how can you guarantee traffic? Sure, you can give an estimate or an approximate - but guaranteeing is not something you should be doing.
When you make guarantees, it makes you resort to things like sending fake traffic to 'make up' for the guarantee (which it obviously isn't).
While telling a business owner you will send them guaranteed traffic might win them over initially, believe me - they will NOT be happy when they realise your guaranteed traffic does not bring them any revenue/money/new clients. You need to re-work it, because you are already limiting the success of your business right from the start, with this mind set.
Why don't you focus on guaranteeing other things, which are in your control? Things like, you will work on the SEO for X amount of keywords, or write Y amount of blog posts for them, or basically anything else that is in your control.
OR - if you must guarantee, guarantee something which you KNOW you will achieve. I have a website generating me about 90 visitors per month (local lead gen site). If I was forced to guarantee something, I would say I guarantee 20 high quality prospect visits per month. That's about 25% roughly of what I get currently for the last several months so there is no problem. I honestly wouldn't guarantee anything like that though, unless I needed to.
Further, if you really do want to guarantee - then go ahead, but keep your promise, at least. Give them the free service, if they earn it (by your promise). Deceiving people actively won't get your far.
PS: Visitors are nothing in the offline industry. Getting the visitors to call is where the money is at. What's the point in sending them 100 visitors (**real visitors**) if still not many of them call.
You should tell them you are going to give them the best chance to appear in their local area for their business related search terms, and they are likely to get calls from people looking for their service or product in their area. Then you explain to them how these leas are HOT because they're already looking for their service. At least this way it is the truth, because the leads you generate should indeed be very hot and laser targeted. No lies there, and if you do the work - it should all go as planned.
All in all, I think you need to lose the visitor guarantee - because even if you do get them the 100 visitors, they're probably going to be assuming that equals 100 callers - because they probably have no idea about conversion rates. Realistically, out of 100 semi targeted visitors you might get 5-10 calls made (going by my own experience in Dental niche initially - now I am up to around 30% conversion).
Good luck.
