I believe your sales funnel will suffer from a lower conversion rate due to your current domain name. A rebrand or upgrade should save you money in the long run and help you gain traction here and now.
Sorry for the negative remarks. I don't bash domains simply to gain clients. The domain is an important component in your funnel, and this one really is a bit off-putting (while a person looks at it) as well as forgettable (once they look away). Replacing Appflashexplainervideos.com is a move toward greater efficency.
