Edit a video- Require highly skilled and experienced

I own a laser tattoo removal business. I have already had a professional create an introduction to my business and services. The video shows inside my business, the employees, the clients and gives an insight into the general business. Since we are a new business and have only just opened, it is important to convey a professional and 'clean clinical' workplace. Like i said- the video has ALREADY BEEN CREATED - I will supply the working file. A preview of the file can be watched here- [login to view URL] What i need: >In the video at 0.07 - 0.08 there is some visible mould on the ceiling. I would like to some how edit this out of the frame > I would like to add a couple of banners to slide in an out of frame with some text- this video is an example of what i mean by 'banners to slide in an out' - go straight to 0.30 [login to view URL] I would like the banner to be our logo colour fading as the one in the video >Make the video look more high quality >I want to have the following information slide in and out of the video 'Sydney's laser tattoo removal specialists' 'World class laser technology' 'it's never been easier' >Perhaps change the first slide to only have the logo and add the address on the last page? >I also want some professional advice as to what may it look better Please read the brief before you apply! I want to be sure you know exactly that i am after and can do the above. Thanks
