question by hnic | Moderate

Hello everyone im new to this forum and new to programming so you can consider me a novice, my question related on 2 things first was that i was creating a website such as www.rent.com or www.apartmenthunterz.com where people could come on my website and for a fee could post there rental units for a fee for each month per unit renting, users coming on to the website could then check these units out for free and also contact the landlords through contact buttons such as yahoo,msn,aim, and skype because unlike the competitor websites i would be going international and think the skype would help people from abroad contact people in the U.S., now to my question what would i need to do or how do i make it so that users can upload pictures of there units and i charge them the fees for example say user 1 wanted to rent his unit but for 2 months and the fee was 29.99 how would i set it up to automatically charge him for these services and allow him access? my 2nd question was since i hear that meta tags are not useful anymore where would i put my target keywords since its useless to use the keyword meta tag? i have alot of keywords that i wanted to use however im at a loss as to where to insert them? lastly this is mostly more of an opinion from the forum i have 3 domain names i bought for this site i want to build but i don't know which one to use they are www.rentbully.com www.renthog.com and www.apartmentless.com what would you guys suggest would be a catchy profitable domain name? any and all help would be greatly appreciated, thanks ~bless~
