With a few exceptions, you'll almost always make more $$ with trials than without.
I push one site really hard that only converts 20% of the trials some months, but every way we've tested it, it makes more $$ with trials than without, both in the short and in the long term.
With a solo girl amateur site, I wouldn't charge too much. No more than $30 but most solo girl amateur sites stay in the $20-$25 range.
I think the main reason for this is that most of your members are also members at other sites. They very well may think you're the greatest thing since sliced bread, but you can't be on the cam 24/7, so when you're not putting on a cam show they have something else they fall back on to get their "relief".
The hangups of trials? Make sure you have a good htaccess file or a script running on the server side to prevent the "leech" programs from downloading your entire members area during the trial period.
Also, if I were you, I'd watermark EVERY SINGLE ONE of my pics and mpegs with the URL of your site.
There are going to be people who steal your content and put it on bbs boards etc, at least if you have your URL on the content you can get a few extra members out of the deal.
That's my
