vBulletin Mods Adjustment

Hello freelancers, I've got 2 mods, which were designed for vBulletin v4.1.x, they work quite all right with vBulletin v4.2.x, but there're very small bugs, e.g. 1 link doesn't appear somewhere, etc. These mods aren't anything extensive and the job should get done in less than 20 mins., if you know your way around vBulletin, so please, don't bid crazy sums (I'm not going to pay more than $50), because the mods are really small. I require to work with someone, who actively works with vBulletin, not with someone, who saw vBulletin a year ago or so and with someone, who has Skype and fluent English. Regards, John Harper
