Home PC user software

We are looking to buy, outright, a range of software products that we can then sell, as downloads to home PC users.
The software products that we are interested in will appeal to PC users aged from 18 • 35 and be able to be priced at £10 - £25 per programme, for the user to download and then use.
We want to be able to buy software solutions outright, branded, and then sell them to our customer base.
At this stage we have a very tight budget, but this budget will grow and develop so the person with whom we link at this stage could see a very lucrative relationship develop over the coming months. Initially we would be looking to pay around £200 for a software product (outright and in our ownership) but there will be more business to come and are happy to increase the budget when it does.
We would happily consider apps’ for mobile phones too. Also games and other simple software packages. We do want to own the software outright; to be able to sell (by users downloading) as many copies as we wish.
We will also have a requirement for a programmer to secure’ some software we already own (written in visual basic) to enable security tags to monitor customers downloading and using it, one licence at a time.
Software that would be ideal for us could include: software with mobile phone applications, logic, strategy games, brain training style games that can be used on a mobile phone. Etc etc.
So lots to talk about, starting with a requirement for a software product/s that we can buy outright and will appeal to average home PC users.
