OpenCart : extensions and template install/tweak

We have an installation of Open Cart which we need some small work done on. We have installed 2 mods, one for offline credit card processing and one for emailing PDF invoices, but we need someone to check and correct a couple of small things (the offline credit card for example shows up twice in the sales menu, and the PDF invoices doesnt show up in the Orders pages). We also need a template installed which we purchased, and then need it configured and modified for us. Simple work really, so bid accordingly. We have set the project to 4 hours but expect it won't take anywhere near that long.
