I would suggest starting off reselling to the companies due to the fact that it allows you to control how much you bill them for the combined design and hosting portions. It also gives you another value-added offering for your customers. This way you can give them an all-inclusive package that includes both design and hosting. Another positive aspect to reselling is you’re not solely responsible for providing technical support-your clients can still have the option to call the hosting company for help if they needed it. At the company I work for we offer a 30% discount on all hosting accounts you bring in if you’re a reseller, or if you preferred we could simply give you credit in the form of free hosting for every additional plan. Feel free to contact me if you needed any of this cleared up, I hope it helps!
