Hey AK, welcome to the forum. Go to Seedsman.com or Seedsupreme.com, and there's a column on the left where you can type in what you're looking for. Sounds like you want sativa-heavy hybrids as opposed to indica heavy.
Sativa's more the creative, get shit done, head high, and indica tends to be the pain-killing, relaxing, sedative, or "couch-lock" strain. And of course, get feminized seeds so you won't have to worry about males pollinating.
And read the GWE site from top to bottom 3 or 4 times. I'm kinda kidding, but it does require a degree of learning so you don't run into all the pitfalls that can befall a cannabis grower. I'd say study up the basics of how you want to grow--soil, coco or hydro--and learn how you're going to do it. Don't blindside yourself later on.
With all the hybrids out now, you can find mixtures of characteristics that will most appeal to you. Look for the sativa dominant hybrids; you'll find what you like. Finally, keep in mind that cannabis strains have different effects on different people, so what one person loves may make someone else edgy and/or paranoid. And what relaxes one may make someone else feel like they're in cement...
