Free posts VS paid posts help?

Hi,
1. currently this is not possible i am afraid, however i will be soon working on code snippet which along with custom fields add-on will allow to first select the Pricings and then based on pricing selection show correct form scheme. This add-on should be ready this month, but i cannot tell when exactly.

2. Each featured advert has advert-is-featured CSS class, so you can customize the featured Ads like this

.advert-is-featured {
    border: 1px dashed green;
}
.advert-is-featured .advert-price {
    color: blue;
    border-color: blue;
}
