Shopkeeper Looking for Equity Investment to Expand Computer Shop

I recently started a business in the field of computer hardware and mobile communication. I want to expand it by providing higher profit margin products/services.

The products my store is offering - mobile prepaid scratch card, mini load, mobile batteries, charger sets, etc. - have low profit margins. I have insufficient variety of hardware and accessories. The business is running well but the products provided have low profit rate.

I want to expand my business by getting involved in much more profitable services like Legal Documentation (Affidavits, Tenancy Agreements, Sale Deeds, undertakings of Power of Attorney, etc.), Internet Cafe, Mobile Sets, and English Language Classroom.

A high ROI of more 25% p.a. is expected.

I have personal experience in documentation and computer hardware and I will honestly run this business providing transparency in all its accounts.

To buy furniture, computers and accessories.

The investor will be 50% profit partner. Expected ROI is more then 35%
