new to web design and need a little advice. I have been learning xhtml and css for a few months now. My plan is to start a local contractor directory in which people pay a monthly subscription to advertise on the site. I would like to be able to monitor the accounts and have set up where advertisers can login and edit their own advertisement page or have us do it. I would like a similar setup how craigslist uses in which you click on categories and it takes you to listing for that category. I have seen some software or scripts in which you can manage listings but im unfamiliar with how i would apply these and i dont really like the templates as i feel i would need a custom look because most sites that use those software templates are free. My question is i am realizing this is beyond scope of html and css i guess so what should i learn or what would be easiest way to have a directory i can manage and see stats? also would like for advertisers to buy advertisement directly on website. Is this something i could do myself or is it more elaborate in which i should get some outside help? thanks in advance
