IMO you should use your hard earned $$$ to buy food and a few sups rather than paying a trainer. Just search around in the forums to learn what you need to know. There are always people around who will help for free. As for losing 20-30lbs, I'd need to know a little more. At 5'10" & 260lbs you're either a monster or prob have a good bit of BF. You know your body better than me, so you'll have to decide on how extreme you're going to have to get to drop that extra poundage. Try re-evaluating your diet first off. Getting your ratios something like 40P/40C/20F would work well for me. If you need something more drastic consider CKD. Anyhow, this is just a start. Good luck with your goals!
