Make a trailer for my Sci-Fi book

Hello, my name is Roman and I would like a trailer for my book but I am not sure where to find right person for it. I wrote a sci-fi book and english translation is being finished at this moment, within few weeks it should be done and getting ready to be printed. When it gets finished I would like to start promoting it but I am out of promotional materials. Here is the trailer I made myself for Slovak version. [login to view URL] I would like to upgrade it a bit, add some more dynamic and movements. Book trailer I really like is this: [login to view URL] I dont expect same thing of course, I have limited resources as well as limited promotional material. All I have is this (these are bit outdated, I would provide originals if we agree on cooperation): [login to view URL] Talking about budget, I am open to offers, I dont have a budget of hundreds of Euros but on the other hand I dont want it to be done for 5€, it would be best if we could move in range of about 100€ more or less. I would provide basic script and narative, I would of provide everything other that would be necessary and I am also willing to help as long as my skill set alows it. I would expect you to maybe smoothout the script a bit or give me some suggestions also I am open to suggestions in any way. I would like to find someone who would be able to cooperate with me in the future on more of my projects like this. Hopefully I didnt forget about anything. Thank you in advance, have a nice day and best reggards Roman Porubský
