Bike It in Paisley would be my recommendation. My son went through them and I found them to be very good at what they do. At the time it was £60 for a two hour lesson, using their bike so it may be cheaper on your own bike (he had his sr125 but didnt want to use that). I can state they are not rip off merchants and my evidence it this. My mate in work was doing direct access with them and although it was individual lessons he had booked, when the cost reached the amount an intensive course would have cost, his remaining lessons were free. Fair enough he only had 2 more lessons until his test but their honesty and integrity shone through.
