Theme Customization - (Please read before you bid)

Hi Everyone. Please note the following : You are not going to be involved in any Magento function development at all. (I believe the total pages in my current website are less than 10) I have an ongoing Magento website project that is taken care by some professionals who are developing the core functionality of my website. However, I need at this stage just to customize or change the theme of my website All what I need is someone who really knows how to customize themes, play with the CSS files and give me a very nice modern design. I am more into a the simple, formal and very clean design. I have some examples in my mind so message me in private to discuss about these themes in general. I can send you examples of some of the websites that I really liked just to know my taste in general The look as I said should be very professional. This site is e-commerce , not a Blog. Please bear this in your mind I have used the ultimo theme for my current website. We have just applied the theme and changed some colors , so I need now to beautify the site, make it look very appealing to the visitors. I have also drafted some designs on my omnigraffle software when I had sometimes the last two days, but I have always seen that there are a lot of things that are missing, the touch! The touch that is going to make the online store is the key for whomever feel that he can do this change for me. Please do not bid if you do not have the ideas because I do not have enough ideas to give it to you. You need to be fully equipped with real amazing designs that are outside the box. In addition to this, my aim is to reduce the buttons on the header, for example, there is no need to put sign up, login while the account button is enough to do this function. I just want also to remind you that I have already bought the ultimo theme and I know that it can be customized, however, if you feel that there is no way but to have another theme then let me know. I am not really into building theme from the beginning due to the cost, however, if you have ready made themes that you want me to have a look at, then please let me know. My logo is available in PSD format. This means that if you really want to change the color of the logo to make things happen, then I really do not mind. I can always keep two logo versions where one is colorful the way you see it on my website and the other logo per your own design. One final thing, please keep in mind that my website design is high responsive, this means that customizing the css or having a new theme customization should preserve this feature in my website. (Taking a backup of the site is always a great idea) Please list all of your theme samples that you have designed in you previous experience because that is going to be one of my judgements in selecting the right developer Also it will be great idea if you can suggest some designs
