Sorry WWJD... There is NO "Fake" Professional results... Not really... You can get sorta close, but photo's like the one you posted are not just a matter of point and shoot. If it were so easy there would be No such thing as professional photographers. There is just as much Art (maybe More) as Science involved, it just isn't all that simple. Bulletrain nailed this pretty well above.
You'll find your equipment lacking almost instantly, I love my S500 but I have no illusions regarding it's abilities or lack of. Lighting is going to be your enemy just like Bullet was saying... At a minimum you will need some external lighting, and a slaved/remote flash. I use the 3600HSD Flash with my Minolta and it works OK for filling shadows and avoiding the hot spots common with a small digital Camera. So if you really want to produce production quality stuff a new camera will really help... OK OK enough of the Cant's...
I bought 4 el cheepo Clamp-on old school shop lights. Remember these? With the aluminum reflector and clip base? Dad Prolly had a few. Anyway, you can pick them up for about $2.99 each. These you pack with just about anything you want depending on what you want. Just pay attention to types of bulbs. Halogens, VS Flourescent, VS Incandescent. They are all useful depending on the look your after. With the clamps they can be positioned just about anywhere and it's not too hard to build reflectors for them... Experiment and play around, you'll find things you like and work well.
Outdoors... using the sun is a good way to go, just do what BT mentioned...
After you capture your images and got things working out for you that way your going to need a photo editor... Photoshop is the only way to go... IMHO Then you'll prolly need a layout program though you could get away at this point with just taking your 300DPI images and a mockup to a graphics shop (Not Kinkos), explain to them what is you want to see and let them do the layout for you... It's frequently more cost effective and quicker...
So not saying that what your after is impossible, I guess... Not really... But it's going to be a poop ton of work to get it right, but it should also be fun... And now that I think about it, you really could get away with the S500... But it's going to be a case of working to the camera's strengths... I do recommend that your wife be present for any Nude/Bikini shoots... Trust me on this, it will make things move along much better and really it puts everyone at ease and you can get better results... Plus, you will prolly need the help.
Lastly Models... Strippers are a fuggin pain in the ass and not worth the time, effort, and Drama. If there is a University near you that would be a good place to start, and again, your wife will come in very handy...or girlfriend... Hell Both if your properly squared away.... I mean handy in finding willing models who will work for cheap.
I can prolly lend some Photoshop tips or help if you need it when the time comes.... But make certain you capture good images, no amount of photoshopping can clean and perfect what isn't there....
I'm rattling I know... Sorry about that...
