I couldn't get your site the first few times I tired but finally was able.
I do like the color-y OBV logo in the top right quite a lot but I think it would be better suited as the main logo for the whole site - on a plain white header with your links more visibly interjected there, perhaps bigger, bolder and with more color. You also have a great company name and numerous side-projects/companies from what I can see -I would love to see them blended together a little more smoothly - highlighted more so they stand out.
You asked about the ads so I'm going to be bluntly honest and say that unless you are advertising your own services it just detracts from the professionalism of your site so much. The ads that are for your own services, it's not clear that they're yours because they're mixed in with ads for eBags and hosting companies.
I would spend some time cleaning up the formatting and fonts on your pages - it's so hard to tell where I'm supposed to look first and where to go next. You need to give your visitors a clear path to follow from Intro to Services to Contact - tell them what they want to know right away, get them hooked and interested in more info and get them to the contact page before they lose interest and click off.
Less is more when it comes to a business site so really look at all the little moving parts and extras you have scattered around and decide if they add value to your potential client's visit. If the answer is no - get rid of it!

There is so much going on the main content of your pages seems almost lost - bigger font might help but that's not really the core of the issue which is page clutter.
I hope that helps - I'd love to see what you do with it, so keep us posted.
