convert iweb website into joomla and optimise

hi I have made a website in iweb jennymcevoy.com. i am unable to install an appointment scheduler into the iweb website. the iweb website doesn't appear to look good on all browsers and i cant optimise it for search engines easily and I need it to load quickly and look modern and professional. i am using mac osx 10.5 laptop So i would like my current iweb website to be converted into joomla. the appointment scheduler is in stivasoft and seems quite straight forward however I just cant get it to work in my book an appointment page in my current website and the company i purchased it from cannot assist, i have tried everything I can think of, so it will also need to be installed on website, the back end on my isp site is already done and working, so this aspect will not be hard. it is two steps. I am on a very tight budget I have an ftp site my website is [login to view URL] it is available to view at present online i have purchased the appointment scheduler from stivasoft/phpjabbers. it is a two step process apparently to install in a normal website and is simple enough as they have done the sql in the back end. however i have built my website using iweb. and nobody can seem to get the appointment scheduler to work on iweb. it is an easy two step process on another website programme. its just iweb is so not user friendly. IWEB is not user friendly and doesnt allow you to gain any visibility in google searches etc. I have built my website using iweb and need to convert it to a site that will easily allow me to optimise it for search engines, and update it if need be as I have apple mac osx 10.5 operating system as I will be installing other new scripts from phpjabbers in future and updating when necessary. This job is as follows: convert or rebuild my iweb site into joomla install a photo rotater with a few different albums to choose from within my website(ie to show pictures) in front page and also a couple of other pages to make website look professional and easy for me to update when i need to. To ensure my website loads very quickly ensure it is working online and active when finished viewable in all browsers and mobile phone devices install the appointment scheduler script and install 24 cron jobs. (i have the instructions to do this but it needs to be done 24 times ie once per hour on servage) and fully tested to ensure it is working install meta tags and optimise my webpage so that it sits high in the ratings of google etc. IWEB only gives you the option of top menus, i would like the current menu system at top to have drop down menus detailing what is currently on those existing pages(the menus i currently have on side of each page). I would like it to be modern and easily viewable on mobile devices and all web pages and adhere to all guidelines for online optimization etc please? I agree it is dated. also put in an analytics system so that I know how many people have viewed my pages etc. and where they have came from so i can see which streams of advertising is working and how I am attracting visitors who purchase to my website I wish to own all my the rights to my website and all work done thanks very much jenny
