Small business funding

I have started this company a year ago because neither me nor my husband could find employment. We offer medical standby at schools my husband is a qualified medic so he goes to most of the events so its owner managed. We want to expand but need funding to do so medical equipment is very expensive and to be able to get more business and bigger events we need certain equipment... Its not financially viable at this stage to borrow the money as at this moment the business is seasonal we only do business when schools are in their sports seasons. We also subcontractor for other sports events companies and events companies. We need to buy ESG's extra immobilizing equipment and medical consumables to be able to expand
